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

## Ans 7:

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 12:

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 13:

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 18:

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 19:

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 24:

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 25:

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

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

## Ans 33:

Class : Class 6

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

## Ans 35:

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 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 39:

Class : Class 8

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

## Ans 42:

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 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 46:

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 47:

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 48:

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 50:

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 54:

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 56:

Class : Class 7

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

## Ans 57:

Class : Class 8

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

## Ans 60:

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 62:

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 64:

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 66:

Class : Class 8

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

## Ans 69:

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 71:

Class : Class 5

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

## Ans 73:

Class : Class 6

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

## Ans 75:

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 76:

Class : Class 8

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

## Ans 78:

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 80:

Class : Class 8

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 81:

Class : Class 9

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

## Ans 86:

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 87:

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 89:

Class : Class 5

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

## Ans 90:

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 91:

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 92:

Class : Class 6

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

## Ans 97:

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 98:

Class : Class 6

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

## Ans 100:

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 101:

Class : Class 9

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

## Ans 102:

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.
