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.

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

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

## Ans 53:

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 71:

Class : Class 5

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 72:

#### Edit Post

Class : Class 9

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 73:

Class : Class 6

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

## Ans 74:

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 75:

Class : Class 6

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

## Ans 76:

#### Edit Post

Class : Class 5

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 77:

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 78:

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.

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.

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 114:

#### Edit Post

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 115:

#### Edit Post

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?
