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

Class : Class 7

Class : Class 5
REeeeeeeeeeeee

## Ans 4:

Class : Class 9
the answer is c because 0 is a natural number and 1 is the only multiple of itself

## Ans 5:

Class : Class 8
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.

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

Class : Class 3

Class : Class 10
the smallest multiple of a number is itself

Class : Class 4

Class : Class 4
nope!

Class : Class 1
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

## Ans 12:

Class : Class 6
There is no such 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.

Class : Class 8
it may be c or d

## Ans 15:

Class : Class 6
Ans is because 0 is not a natural number and 1 is a factor of every number not a multiple

## Ans 16:

Class : Class 7
i think it should be c

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 18:

Class : Class 6
the answer is obviously C because 0 is the only number which is it but it is a whole number

Class : Class 5

## Ans 20:

Class : Class 6
Yeah it is c) OMG there are so many comments for this question!!

## Ans 21:

Class : Class 8
MY FIRST COMMENT WAS WRONG ... I WANTED TO WRITE -THE WHOLE NUMBER THAT IS THE FACTOR OF EVERY NUMBER IS _______.

## Ans 22:

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 23:

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.

Class : Class 5

## Ans 25:

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 26:

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 27:

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 28:

Class : Class 6
It should be c. There is no such number. And 1 is factor not multiple!!!

## Ans 29:

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 30:

Class : Class 5
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 ?????

Class : Class 7
C

Class : Class 6

## Ans 33:

Class : Class 9
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.

Class : Class 7

## Ans 35:

Anwer is C. 1 is a factor of every number and not the multiple

## Ans 39:

0 is not a natural number

## Ans 40:

Class : Class 5
0 is the answer but it is showing 1 as answer. Problem!

Class : Class 7

## Ans 42:

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 45:

Class : Class 7
The answer is a because 0 is a natural number and is a multiple of every number. for eg- 19*0

Class : Class 8

## Ans 47:

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.

Class : Class 6

## Ans 49:

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 62:

Class : Class 8
yes the answer is wrong on the SOF portal . It is showing answer B but the correct answer is C

## Ans 63:

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 64:

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.

Class : Class 5
nope

## Ans 66:

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.

Class : Class 8

## Ans 68:

Class : Class 6
Answer is D. 1 is not a multiple but factor of all natural numbers.

## 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 70:

Class : Class 6
ccccccccccccccccccccccccccccccccccccccc

## Ans 71:

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 72:

Class : Class 6
THERE IS NO SUCH NUMBER. THE SMALLEST MULTIPLE OF A NUMBER IS THE NUMBER IT SELF.

## Ans 73:

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 74:

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 75:

Class : Class 7
zero is not a natural number, so A is incorrect. The correct answer must be D

## Ans 76:

Class : Class 6
it should be C not B

Class : Class 6

## Ans 78:

Class : Class 7
1 is the factor of every number not multiple he should learn.

## Ans 79:

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

Class : Class 7
I agree

## Ans 81:

Class : Class 5
the question is the wrongthe correct option is cand the smallest multiple of every number is the number it itself

## Ans 82:

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 83:

Class : Class 5
The question is wrong....1 can be factor of all natural numbers not the multiple

Class : Class 10

## Ans 85:

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 86:

Class : Class 5
answer is c as 0 is not a natural number and 1 is a factor of every number,not multiple

## Ans 87:

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

Class : Class 6

## Ans 89:

Class : Class 8
The answer should be C because 1 is multiple of only 1, not any other number but, it is a factor of every number

Class : Class 5

## Ans 91:

Class : Class 7
every number multiplyied by 0 is 0 so its (A)

## Ans 92:

Class : Class 7
(C) (C) (C) (C) (C) IS CORRECT

## Ans 93:

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.

Class : Class 6

Class : Class 8

Class : Class 9
c

Class : Class 5
sure it is C

## Ans 98:

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 99:

Class : Class 7
This is impossible 1 is a factor of every number not a multiple

Class : Class 6

## Ans 101:

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 .

Class : Class 5
Maybe c
