Subject :IMO    Class : Class 5

The natural number which is a multiple of every number is ______.

A 0
B 1
C There is no such number
D None of these


answer must be c

Ans 1:

Class : Class 10
in fact C should be the correct answer as there can not be any such number. By taking D as the correct answer we are ,at the same time, denying the statement given at C.

Ans 2:

Class : Class 6
Ans is because 0 is not a natural number and 1 is a factor of every number not a multiple

Ans 3:

Class : Class 7
zero is not a natural number, so A is incorrect. The correct answer must be D

Ans 4:

Class : Class 5
just clearing, 0 is correct but it is not a natural number tho. i think the answer should be C and why this fu*kin trainer shows B ?????

Ans 5:

Class : Class 7
This is impossible 1 is a factor of every number not a multiple

Ans 6:

Class : Class 6
the answer is obviously C because 0 is the only number which is it but it is a whole number

Ans 7:

Class : Class 8
Answer will be 0 because 2*0=0,5653453*0=0,4765868756733465358678757646535436536854786*0=0

Ans 8:

Class : Class 6
how can 1 be a multiple of a number accept 1 itself . I suggest the human to write all tables 1000 times

Ans 9:

Class : Class 9
it should be c as their is no number that is the multiple of every number

Ans 10:

Class : Class 9
yes the answer is wrong on the SOF portal . It is showing answer B but the correct answer is C

Ans 11:

Class : Class 5
The correct answer is C. There is no such number.

Ans 12:

Class : Class 6
Yeah it is c) OMG there are so many comments for this question!!

Ans 13:

Class : Class 6
it should be C not B

Ans 14:

Class : Class 8
C is the answer. I don’t understand how 1 can come.

Ans 15:

Class : Class 6

Ans 16:

Class : Class 8
CORRECT ANSWER IS D BECAUSE THE BECAUSE THE SMALLEST MULTIPLE OF A NUMBER IS THE NUMBER ITSELF.

Ans 17:

Class : Class 6
There is no such number.

Ans 18:

Class : Class 2
Whoever wrote a or b is foolish. C is the answer.

Ans 19:

Class : Class 9
maybe a.

Ans 20:

Class : Class 5

Ans 21:

Class : Class 3

Ans 22:

Class : Class 10
0 is the answer

Ans 23:

Class : Class 10
nope

Ans 24:

Class : Class 4
nope!

Ans 25:

Class : Class 6
THERE IS NO SUCH NUMBER. THE SMALLEST MULTIPLE OF A NUMBER IS THE NUMBER IT SELF.

Ans 26:

Class : Class 9
the answer should be c because 1 is a factor of every number and the smallest multiple of any number is the number itself

Ans 27:

Class : Class 5
And.will C

Ans 28:

Class : Class 5
it should be c as 0 is a whole number while 1 is a natural number but it is a factor of every number not a multiple.

Ans 29:

Class : Class 6
It should be c. There is no such number. And 1 is factor not multiple!!!

Ans 30:

Class : Class 5
it must be c as 1 is the factor of every number not multiple!

Ans 31:

Class : Class 5
MASTER ANSWER !!!!!!!!!!!!! ANS IS C.......... .

Ans 32:

Class : Class 6
C is the correct answer

Ans 33:

Class : Class 10
Anwer is C. 1 is a factor of every number and not the multiple

Ans 34:

Class : Class 5
The answer should be A or B since if the answer A, that is 0, it can be the answer as any number multiplied by 0 is equal to 0. But, if the answer is B, that is 1, it can be the answer if the question has been framed wrongly, that is, if the question would have been "What is the common factor of all the numbers" since all numbers are divisible by 1. But how could the question possibly go so horribly wrong?

Ans 35:

Class : Class 9
The answer is definitely c "There is no such number" as 0 is not a natural number but a whole number. Secondly though 1 is a natural number it is only a multiple of itself and not a multiple of every number.

Ans 36:

Class : Class 6
Answer should be corrected, 1 is factor of any number, but not multiple of every number. Correct answer is C.

Ans 37:

Class : Class 8
C

Ans 38:

Class : Class 9
MY FIRST COMMENT WAS WRONG ... I WANTED TO WRITE -THE WHOLE NUMBER THAT IS THE FACTOR OF EVERY NUMBER IS _______.

Ans 39:

Class : Class 5
definitely the answer is c

Ans 40:

Class : Class 7
the ans: is c not b

Ans 41:

Class : Class 10
The answer is C.

Ans 42:

Class : Class 6

Ans 43:

Class : Class 8
Either the question should be ''The natural number is a factor of every number is ________________.'' or the solution that SOF Olympiad Trainer has given the wrong output. The answer should be C. Please change the output SOF Olympiad Trainer.

Ans 44:

Class : Class 9
wrong ans shown

Ans 45:

Class : Class 5
answer is c as 0 is not a natural number and 1 is a factor of every number,not multiple

Ans 46:

Class : Class 1
Guys I am just clearing a doubt I am not sure though. The Ans should be D. Because the natural number which is the multiple of every number is the number itself. Like:1x1=1 2x2=2. Please tell me if I am wrong and make me understand. Thank u

Ans 47:

Class : Class 6
The answer is C.

Ans 48:

Class : Class 9
Answer is C because 1 is a natural number and also the FACTOR of every number. It isn't possible that B is the answer for multiple.

Ans 49:

Class : Class 6
Hi guys the answer should be c. Some people say its 0 but 0 is not a natural number.

Ans 50:

Class : Class 5
The question is wrong....1 can be factor of all natural numbers not the multiple

Ans 51:

Class : Class 4
The correct answer is 'c' because there is no such number that is a multiple of every number and 1 is the factor of every number and not the multiple .

Ans 52:

Class : Class 7
Answer is C . If 1 has to be the answer , the question should be " The natural number which is a factor of every number is "

Ans 53:

Class : Class 8
it may be c or d

Ans 54:

Class : Class 6

Ans 55:

Class : Class 6
it is 0 its the answer 0 is the multiple of every number see 1 multiplied by 0 is 0 then 1 multiplied by 1 is 1 so 0 comes before one and it comes in every numbers table but we dont list

Ans 56:

Class : Class 7
The correct answer is C

Ans 57:

Class : Class 6
c is the ans.

Ans 58:

Class : Class 7
Look, 1 is the factor of every number, not a multiple of everyone! 0 can be multiple, as 5*0 = 0 and 16*0 = 0. However, 0 is a whole number and not natural number, so the correct answer should have been "c" but, if they said factor instead of multiple, it would be "b" and if they said whole number instead of natural number, the answer would be "a"

Ans 59:

Class : Class 6
the correct answer is C

Ans 60:

Class : Class 6
FACTOR OF EVERY NUMBER IS 1!!!!!!!!!!!!!!!!!!!!!!!!!!! 1 IS NOT THE MULTIPLE OF EVERY NUMBER!!!!!!!!!!!!!!!!!!!!!!

Ans 61:

Class : Class 8

Ans 62:

Class : Class 5
THE ANS IS that there is no such number

Ans 63:

Class : Class 5
0 is the answer but it is showing 1 as answer. Problem!

Ans 64:

Class : Class 6
Is 0 a natural number? Well 1 can never be the MULTIPLE of every number. 1 is the multiple of only itself.

Ans 65:

Class : Class 8
the answer can't be B as every whole number is the multiple of 1 but 1 is not the multiple of any number.

Ans 66:

Class : Class 5
The answer is C. One is not a multiple of every number

Ans 67:

Class : Class 5
ans B if you don't know then scratch your brain

Ans 68:

Class : Class 9

Ans 69:

Class : Class 6
1 is a factor of every number not a multiple . there is no such number as the smallest multiple of a number is the number itself

Ans 70:

Class : Class 5

Ans 71:

Class : Class 8
0 is the answer

Ans 72:

Class : Class 7
the correct answer is c

Ans 73:

Class : Class 3
The answer is C

Ans 74:

Class : Class 9
The answer is C because 1 is a natural number but not a multiple of every number and 0 is a multiple of every number but it is not a natural number

Ans 75:

Class : Class 6
1 is the factor of every number not a multiple.The answer should be (A)

Ans 76:

Class : Class 7
This is impossible how can a multiple of every number be 1!!!!

Ans 77:

Class : Class 5
the ans is c because 1 is a factor of every no. not a multiple.the answer would be 0 if they asked for a whole no.

Ans 78:

Class : Class 6
0 is not a natural number

Ans 79:

Class : Class 9

Ans 80:

Class : Class 5
REeeeeeeeeeeee

Ans 81:

Class : Class 9
the answer is c because 0 is a natural number and 1 is the only multiple of itself

Ans 82:

Class : Class 10
the smallest multiple of a number is itself

Ans 83:

Class : Class 8
The question is wrong. It should be: The natural number which is a factor of every number.

Ans 84:

Class : Class 5
c

Ans 85:

Class : Class 3
1 is a factor of all natural numbers .It is not multiple of all numbers

Ans 86:

Class : Class 8
I agree

Ans 87:

Class : Class 6

Ans 88:

Class : Class 6

Ans 89:

Class : Class 3
The answer is C as there is no such number that is a multiple of every number. If it were a factor then it would have been correct

Ans 90:

Class : Class 8
Master Answer Admin from Revisewise Noida please resolve this doubt and provide explanation. Answer should be C because 0 and 1 can never be multiple of any number. 0 multiplied by any number is 0 only, thus it can never be a multiple. 1 multiplied by any number is the number itself, but any number multiplied by another number is not 1, thus even 1 is not the answer. By choosing Opt. D we deny the fact that there is no such SPECIFIC number (which means we say there is a specific number). So ONLY Option C is correct.Correct, we must report this as error because our doubt has not yet been clarified. SOF PLEASE PLEASE help

Ans 91:

Class : Class 5
The correct answer is C

Ans 92:

Class : Class 5
The ans is D because the number that is the multiple of every number is the number itself. Ex- 6 x 1 = 6

Ans 93:

Class : Class 4
Kavya Vikas Gatkal from Podar International School JalnaThe answer is c because 1 is a factor of every number not a multiple

Ans 94:

Class : Class 5
The answer would be c because 1 is factor of every number not multiplie if it is a whole number then it will be zero but if it is a natural number then the answer of the final question would be c sir.So hence option c will be the correct answer of the question.

Ans 95:

Class : Class 7
(C) (C) (C) (C) (C) IS CORRECT

Ans 96:

Class : Class 7
1 is the factor of every number not multiple he should learn.

Ans 97:

Class : Class 7
the answer should be c. 1 is a natural number but it is a factor of every number not a multiple. and zero is a whole no. so it should be whole no. which is a multiple of every no.

Ans 98:

Class : Class 7
Hi guys, according to me, the answer should be zero which is option 'A' because when you multiply any number with zero, the answer will always be zero. Hence, we can say that zero is a multiple of every number.

Ans 99:

Class : Class 7
i think it should be c

Ans 100:

Class : Class 2
The corretct answer is C because there is no such number which comes in all the tables. Multiples are the products of numbers. Then how is it possible that SOF website is showing the answer is 1

Ans 101:

Class : Class 5
the question is the wrongthe correct option is cand the smallest multiple of every number is the number it itself

Ans 102:

Class : Class 6
Correct answer should be C. 1 is a natural number but it's not multiple of every number, rather it's factor of every number.

Ans 103:

Class : Class 9
c

Ans 104:

Class : Class 5
Maybe c

Ans 105:

Class : Class 9
How is the answer "B".IF THE QUESTION WAS "a number which is a factor of every number, then the answer is b because all numbers can be multiplied by one .but in this question the correct answer is c

Ans 106:

Class : Class 4

Ans 107:

Class : Class 8
0 is the answer

Ans 108:

Class : Class 5
the ans is C dude! how the sh*8 is that 1?! coz' 1 is the factor of every number, man. are we doing timepass here??

Ans 109:

Class : Class 6
Agreed , answer is C. 1 is not a multiple of every number, it is a factor of every number. There is a error in the answer system.

Ans 110:

Class : Class 5
It should be d . Please tell us master admin

Ans 111:

Class : Class 5

Ans 112:

Class : Class 9
None of the above- option is the correct answer. I think we should report it as error instead of discussing on forum so much. See SOF's answer is wrong so there they shown no solution. They themselves know their mistake but not correct it. There are many mistakes such as this. I think next time SOF improves.

Ans 113:

Class : Class 6
Answer is D. 1 is not a multiple but factor of all natural numbers.

Ans 114:

Class : Class 5
nope

Ans 115:

Class : Class 6
the answer is c

Ans 116:

Class : Class 8
you guys are right

Ans 117:

Class : Class 5
I mean ans is c

Ans 118:

Class : Class 7
The correct answer is C

Ans 119:

Class : Class 9
The answer is C because 1 is the factor of every number, not the multiple. And 0 is the multiple of every number but it is not a natural number

Ans 120:

Class : Class 8
SOF should correct the answer it can create confusion among the kids 0 is a whole number, 1 is factor of every number so definitely there is no such number whose multiple is 1

Ans 121:

Class : Class 5
0 is the answer

Ans 122:

Class : Class 2
the answer is c

Ans 123:

Class : Class 5
C because 1 is a common FACTOR of every number, not multiple. And 0 is a whole number and I doubt any other number would be a multiple for every number so it's gotta be C.

Ans 124:

Class : Class 5
This SOF is bad and mad

Ans 125:

Class : Class 7
every number multiplyied by 0 is 0 so its (A)

one is not a multiple of every number , but every number is a multiple of one, . zero is not a multiple of every number . answer is definitely C

Ans 130:

Class : Class 7
C

Ans 131:

Class : Class 4
The answer should be C. If it was a whole number, then it would have been 0. The question seems to be framed wrongly. The question should have been, " The natural number which is a factor of every number is 1". The answer is wrong.

Ans 132:

Class : Class 6
foolish

Ans 133:

Class : Class 4
The answer should be C

Ans 134:

Class : Class 9
THE ANSWER IS WRONG IF THE ANSWER IS CORRECT ,THEN THE QUESTION MUST BE -THE WHOLE NUMBER THAT IS THE MULTIPLE OF EVERY NUMBER IS ___.

Ans 135:

Class : Class 5
stupid it is C

Ans 136:

Class : Class 8
0 is the only answer

Ans 137:

Class : Class 4
The answer should be C.

Ans 138:

Class : Class 8
The answer should be C because 1 is multiple of only 1, not any other number but, it is a factor of every number

Ans 139:

Class : Class 5
sure it is C

Ans 140:

Class : Class 8
0 is the answer

Ans 141:

Class : Class 5
The correct answer is 'C' as 0 is the multiple of every number and it is not a natural number. So, the answer is ' There is no such number '

Ans 142:

Class : Class 6
The answer is wrongly given at the back . It should be C

Ans 143:

Class : Class 7
The answer is a because 0 is a natural number and is a multiple of every number. for eg- 19*0

Ans 144:

Class : Class 8
the correct answer should be option c.

Ans 145:

Class : Class 5
The answer will not be 1 as 1 is a factor of every number, not a multiple. The multiple of every number is infinite, not the 2nd Natural number.
