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

## Ans 6:

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 7:

Class : Class 4

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

## Ans 8:

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 12:

Class : Class 6

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

## Ans 13:

Class : Class 5

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 14:

Class : Class 8

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.

Is 0 a natural number? Well 1 can never be the MULTIPLE of every number. 1 is the multiple of only itself.

## Ans 18:

## Ans 24:

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

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 34:

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

## Ans 35:

Class : Class 5

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 36:

#### Edit Post

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 38:

#### Edit Post

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 39:

#### 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 40:

Class : Class 3

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 41:

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.

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 52:

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.

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

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.

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 69:

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 70:

## Ans 71:

## Ans 74:

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

## Ans 76:

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 77:

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 78:

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
