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

Ans 4:

Class : Class 5
REeeeeeeeeeeee

Answer will be 0 because 2*0=0,5653453*0=0,4765868756733465358678757646535436536854786*0=0

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

Ans 7:

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

Ans 8:

Class : Class 8
it may be c or d

Ans 9:

Class : Class 2
the answer is c

Ans 10:

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

Ans 11:

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 12:

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 13:

Class : Class 8
C

Ans 14:

Class : Class 6

Ans 15:

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

Ans 16:

Class : Class 4
nope!

Ans 17:

Class : Class 7
C

Ans 18:

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

Ans 19:

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

Ans 20:

Class : Class 9
c

Ans 21:

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

Ans 22:

Class : Class 6
There is no such number.

Ans 23:

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

Ans 24:

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

Ans 25:

Class : Class 8
0 is the answer

Ans 26:

Class : Class 6
foolish

Ans 27:

Class : Class 8
you guys are right

Ans 28:

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

Ans 29:

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 30:

Class : Class 5
definitely the answer is c

Ans 31:

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 32:

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 33:

Class : Class 10
nope

Ans 34:

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 35:

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 36:

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 37:

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

Ans 38:

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 39:

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 40:

Class : Class 9
every number multiplyied by 0 is 0 so its (A)

Ans 41:

Class : Class 10
souvagya saha from de nobili fri dhanbad1is a factor of every number. the answer is c.

Ans 42:

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

Ans 43:

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 44:

Class : Class 5

Ans 45:

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

Ans 46:

Class : Class 5

Ans 47:

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

Ans 48:

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

Ans 49:

Class : Class 5
nope

Ans 50:

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

Ans 51:

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

Ans 52:

Class : Class 7
The correct answer is C

Ans 53:

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 54:

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

Ans 55:

Class : Class 8

Ans 56:

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 57:

Class : Class 3
The answer is C

Ans 58:

Class : Class 5
Maybe c

Ans 59:

Class : Class 9

Ans 60:

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 61:

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

Ans 62:

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 63:

Class : Class 6
it should be C not B

Ans 64:

Class : Class 5
stupid it is C

Ans 65:

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 66:

Class : Class 6
the answer is c

Ans 67:

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 68:

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

Ans 69:

Class : Class 10
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 70:

Class : Class 5
sure it is C

Ans 71:

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 72:

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

Ans 73:

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

Ans 74:

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 75:

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

Ans 76:

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

Ans 77:

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

Ans 78:

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

Ans 79:

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

Ans 80:

Class : Class 5

Ans 81:

Class : Class 6
C is the correct answer

Ans 82:

Class : Class 8
0 is the only answer

Ans 83:

Class : Class 5
answer is c

Ans 84:

Class : Class 6

Ans 85:

Class : Class 7
c is the ans.

Ans 86:

Class : Class 6

Ans 87:

Class : Class 10

Ans 88:

Class : Class 3

Ans 89:

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

Ans 90:

Class : Class 7
the correct answer is c

Ans 91:

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

Ans 92:

Class : Class 7
The correct answer is C

Ans 93:

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 94:

Class : Class 6

Ans 95:

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 96:

Class : Class 10
0 is the answer

Ans 97:

Class : Class 8
0 is the answer

Ans 98:

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 99:

Class : Class 6
ccccccccccccccccccccccccccccccccccccccc

Ans 100:

Class : Class 6
the correct answer is C

Ans 101:

Class : Class 5
This SOF is bad and mad

Ans 102:

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

Ans 103:

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 104:

Class : Class 9
(C) (C) (C) (C) (C) IS CORRECT

Ans 105:

Class : Class 8
0 is the answer

Ans 106:

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 107:

Class : Class 10

Ans 108:

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 109:

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 110:

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 111:

Class : Class 6
The answer is C.

Ans 112:

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 113:

Class : Class 5
0 is the answer

Ans 114:

Class : Class 6

Ans 115:

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

Ans 116:

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 117:

Class : Class 4
The answer should be C.

Ans 118:

Class : Class 5
c

Ans 119:

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

Ans 120:

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

Ans 121:

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 122:

Class : Class 4
1X0 IS 0.2XO 03X0 0easy peasy.

Ans 123:

Class : Class 10
yes the answer is wrong on the SOF portal . It is showing answer B but the correct answer is C

Ans 124:

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 125:

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

Ans 126:

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 127:

Class : Class 7
the ans: is c not b

Ans 128:

Class : Class 7
i think it should be c

Ans 129:

Class : Class 5
And.will C

Ans 130:

Class : Class 4
The answer should be C

Ans 131:

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 132:

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 133:

Class : Class 8
I agree

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 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 136:

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

Ans 137:

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 138:

Class : Class 6
0 is not a natural number

Ans 139:

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 140:

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 141:

Class : Class 10
The answer is C.

Ans 142:

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

Ans 143:

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.

Ans 144:

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 145:

Class : Class 5
The correct answer is C
