## Ans 6:

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

Class : Class 6

## Ans 8:

Class : Class 8
yes the answer is wrong on the SOF portal . It is showing answer B but the correct answer is C

## Ans 9:

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 '

Class : Class 9
maybe a.

Class : Class 6

## Ans 12:

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.

Class : Class 5
I mean ans is c

Class : Class 8
it may be c or d

## Ans 15:

Class : Class 8
MY FIRST COMMENT WAS WRONG ... I WANTED TO WRITE -THE WHOLE NUMBER THAT IS THE FACTOR OF EVERY NUMBER IS _______.

## Ans 16:

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 17:

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

Class : Class 6

## Ans 19:

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 20:

Class : Class 8
you guys are right

## Ans 21:

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 23:

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 24:

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

## Ans 25:

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 26:

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

Class : Class 6

Class : Class 10

## Ans 29:

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 30:

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 .

Class : Class 5
c is the ans.

Class : Class 2

Class : Class 9

Class : Class 8
wrong ans shown

## Ans 35:

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

Class : Class 8

## Ans 37:

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

Class : Class 8

## Ans 39:

Class : Class 6
This is impossible 1 is a factor of every number not a multiple

## Ans 40:

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

## Ans 41:

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

## Ans 42:

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 43:

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

## Ans 44:

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 45:

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

Class : Class 9
c

## Ans 47:

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.

Class : Class 4
nope!

Class : Class 5
And.will C

Class : Class 5

Class : Class 5
sure it is C

## Ans 52:

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 ?????

Class : Class 5

## Ans 54:

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

## Ans 55:

Class : Class 9
Anwer is C. 1 is a factor of every number and not the multiple

## Ans 56:

Class : Class 7
i think it should be c

## Ans 57:

Class : Class 6
0 is not a natural number

Class : Class 3

## Ans 59:

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 60:

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 61:

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

## Ans 62:

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

Class : Class 7

## 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.

Class : Class 5

## Ans 66:

Class : Class 8
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 67:

Class : Class 6
This is impossible how can a multiple of every number be 1!!!!

## Ans 68:

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

Class : Class 7
C

## Ans 70:

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

## Ans 71:

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 72:

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

Class : Class 6

## Ans 74:

Class : Class 6
ccccccccccccccccccccccccccccccccccccccc

Class : Class 5

## Ans 76:

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.

Class : Class 5

## Ans 78:

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.

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

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

Class : Class 6

## Ans 86:

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

Class : Class 7
C

## Ans 88:

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

Class : Class 6
foolish

Class : Class 5
stupid it is C

## Ans 91:

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

## Ans 92:

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 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"

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

## Ans 96:

Class : Class 6
it should be c as their is no number that is the multiple of every number

## Ans 97:

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 98:
