Ans 11:

Class : Class 8
0 is the answer

Ans 12:

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 13:

Class : Class 5
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 14:

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

Ans 15:

Class : Class 5
c

Ans 16:

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 17:

Class : Class 6
the answer is c

Ans 18:

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 19:

Class : Class 5
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 20:

Class : Class 5
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.

Ans 21:

Class : Class 6

Ans 22:

Class : Class 8
you guys are right

Ans 23:

Class : Class 6
The correct answer is C

Ans 24:

Class : Class 5
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 25:

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.

Ans 26:

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

Ans 27:

Class : Class 7
nope!

Ans 28:

Class : Class 5

Ans 29:

Class : Class 4
The answer should be C

Ans 30:

Class : Class 5
This SOF is bad and mad

Ans 31:

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 32:

Class : Class 6
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 33:

Class : Class 5
ccccccccccccccccccccccccccccccccccccccc

Ans 34:

Class : Class 5
The answer is C. One is not a multiple of every number

Ans 35:

Class : Class 6
There is no such number.

Ans 36:

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

Ans 37:

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

Ans 43:

Class : Class 6

Ans 44:

Class : Class 5
It should be d . Please tell us master admin

Ans 45:

Class : Class 6
Anwer is C. 1 is a factor of every number and not the multiple

Ans 46:

Class : Class 6
The answer is C.

Ans 47:

Class : Class 7
the correct answer is c

Ans 48:

Class : Class 5
nope

Ans 49:

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 50:

Class : Class 5
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 51:

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

Ans 52:

Class : Class 8

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 54:

Class : Class 8
0 is the only answer

Ans 55:

Class : Class 6
The correct answer is C

Ans 56:

Class : Class 6
The answer should be C.

Ans 57:

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

Ans 58:

Class : Class 5
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 59:

Class : Class 5
it must be c as 1 is the factor of every number not multiple!

Ans 60:

Class : Class 5
THE ANS IS that there is no such number

Ans 61:

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 62:

Class : Class 5
C

Ans 63:

Class : Class 5
c is the ans.

Ans 64:

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 65:

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

Ans 66:

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 .

Ans 67:

Class : Class 6
Answer should be corrected, 1 is factor of any number, but not multiple of every number. Correct answer is C.

Ans 68:

Class : Class 5
MASTER ANSWER !!!!!!!!!!!!! ANS IS C.......... .

Ans 69:

Class : Class 9
every number multiplyied by 0 is 0 so its (A)

Ans 70:

Class : Class 5
The correct answer is C

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:

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:

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:

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 78:

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 79:

Class : Class 4
1 is the factor of every number not a multiple.The answer should be (A)

Ans 80:

Class : Class 6
C is the correct answer

Ans 81:

Class : Class 5
sure it is C

Ans 82:

Class : Class 5
it should be C not B

Ans 83:

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 84:

Class : Class 5
yes the answer is wrong on the SOF portal . It is showing answer B but the correct answer is C

Ans 85:

Class : Class 6
c

Ans 87:

Class : Class 2
Whoever wrote a or b is foolish. C is the answer.

Ans 88:

Class : Class 5
The answer is a because 0 is a natural number and is a multiple of every number. for eg- 19*0

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
answer is c

Ans 91:

Class : Class 7
The answer is C.

Ans 92:

Class : Class 8
0 is the answer

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

Ans 106:

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 107:

Class : Class 6
foolish

Ans 108:

Class : Class 5
it should be c as 0 is a whole number while 1 is a natural number but it is a factor of every number not a multiple.

Ans 109:

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 110:

Class : Class 2
the answer is c

Ans 111:

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 112:

Class : Class 5
The correct answer is C. There is no such number.

Ans 113:

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 114:

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:

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?
