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 8:

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 10:

Class : Class 8

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

## Ans 13:

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 14:

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 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 19:

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 23:

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 26:

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 30:

Class : Class 6

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

## Ans 32:

Class : Class 8

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 35:

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 36:

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 39:

Class : Class 7

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 40:

Class : Class 9

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

## Ans 41:

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 43:

Class : Class 6

FACTOR OF EVERY NUMBER IS 1!!!!!!!!!!!!!!!!!!!!!!!!!!! 1 IS NOT THE MULTIPLE OF EVERY NUMBER!!!!!!!!!!!!!!!!!!!!!!

## Ans 45:

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 47:

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 51:

Class : Class 7

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 57:

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 61:

Class : Class 5

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 63:

Class : Class 6

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

## Ans 68:

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 71:

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 73:

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 75:

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 81:

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 82:

Class : Class 7

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

## Ans 83:

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 84:

Class : Class 8

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

## Ans 87:

Class : Class 7

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 88:

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 5

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

## 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 96:

Class : Class 5

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

## Ans 100:

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.
