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 2:

Class : Class 5
Maybe c

Ans 3:

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 4:

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

Ans 5:

Class : Class 6
the answer is c

Ans 6:

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 7:

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

Ans 8:

Class : Class 8
0 is the answer

Ans 9:

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

Ans 10:

Class : Class 8
I agree

Ans 11:

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

Ans 12:

Class : Class 10
maybe a.

Ans 13:

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 14:

Class : Class 6

Ans 15:

Class : Class 6
0 is not a natural number

Ans 16:

Class : Class 5
nope

Ans 17:

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

Ans 18:

Class : Class 6
ccccccccccccccccccccccccccccccccccccccc

Ans 19:

Class : Class 6
c is the ans.

Ans 20:

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 21:

Class : Class 7
C

Ans 22:

Class : Class 9
c

Ans 23:

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

Ans 24:

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 25:

Class : Class 3

Ans 26:

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

Ans 27:

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

Ans 28:

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 29:

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 30:

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 31:

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 32:

Class : Class 6
foolish

Ans 33:

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 34:

Class : Class 6
C is the correct answer

Ans 35:

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

Ans 36:

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 37:

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

Ans 38:

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 43:

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 44:

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 45:

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

Ans 46:

Class : Class 5
c

Ans 47:

Class : Class 5
REeeeeeeeeeeee

Ans 48:

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

Ans 49:

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 55:

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 56:

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 57:

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 58:

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 59:

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 64:

Class : Class 5
stupid it is C

Ans 65:

Class : Class 7
the ans: is c not b

Ans 66:

Class : Class 4
nope!

Ans 67:

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 68:

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 69:

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 70:

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

Ans 71:

Class : Class 5

Ans 72:

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

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 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 75:

Class : Class 6

Ans 76:

Class : Class 10
nope

Ans 77:

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

Ans 78:

Class : Class 7
i think it should be c

Ans 79:

The answer should be C.

Ans 80:

Class : Class 7
The correct answer is C

Ans 82:

Class : Class 3
The answer is C

Ans 83:

Class : Class 6

Ans 84:

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

Ans 85:

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

Ans 86:

Class : Class 5
I mean ans is c

Ans 87:

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

Ans 88:

Class : Class 5
And.will C

Ans 89:

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 90:

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

Ans 91:

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 92:

Class : Class 8
you guys are right

Ans 93:

Class : Class 5

Ans 94:

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 95:

Class : Class 8
0 is the answer

Ans 96:

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

Ans 97:

Class : Class 8

Ans 98:

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

Ans 99:

Class : Class 6
it should be C not B

Ans 100:

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

Ans 101:

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

Ans 102:

Class : Class 7

Ans 103:

Class : Class 5
0 is the answer

Ans 104:

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 105:

Class : Class 8
0 is the only answer

Ans 106:

Class : Class 9

Ans 107:

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

Ans 108:

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

Ans 109:

Class : Class 6
The answer is C.

Ans 110:

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

Ans 111:

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 112:

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

Ans 113:

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

Ans 114:

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 115:

Class : Class 8
0 is the answer

Ans 116:

Class : Class 8
it may be c or d

Ans 117:

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 118:

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

Ans 119:

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

Ans 120:

Class : Class 2
the answer is c

Ans 121:

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

Ans 122:

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

Ans 123:

Class : Class 10
The answer is C.

Ans 124:

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

Ans 125:

Class : Class 7
The correct answer is C

Ans 126:

Class : Class 5
answer is c

Ans 127:

Class : Class 9

Ans 128:

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 129:

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 130:

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 131:

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 132:

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 133:

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

Ans 134:

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 135:

Class : Class 5
definitely the answer is c

Ans 136:

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 137:

Class : Class 5
The correct answer is C

Ans 138:

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

Ans 139:

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

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 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
