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

## Ans 22:

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 24:

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.

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 32:

the answer can't be B as every whole number is the multiple of 1 but 1 is not the multiple of any number.

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 50:

The ans is D because the number that is the multiple of every number is the number itself. Ex- 6 x 1 = 6

## Ans 53:

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 55:

#### Edit Post

Class : Class 6

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

## Ans 56:

#### Edit Post

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.

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

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

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.

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 84:

#### 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?

## Ans 85:

Answer should be corrected, 1 is factor of any number, but not multiple of every number. Correct answer is C.

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

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 100:

Class : Class 5

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

## Ans 101:

#### Edit Post

Class : Class 6

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

## Ans 102:

Class : Class 5

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 .
