Ans 2:

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

Ans 3:

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 4:

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

Ans 5:

Class : Class 6
souvagya saha from de nobili fri dhanbad1is a factor of every number. the answer is c.

Ans 6:

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

Ans 7:

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

Ans 8:

Class : Class 6
There is no such number.

Ans 9:

Class : Class 6
foolish

Ans 10:

Class : Class 7
MY FIRST COMMENT WAS WRONG ... I WANTED TO WRITE -THE WHOLE NUMBER THAT IS THE FACTOR OF EVERY NUMBER IS _______.

Ans 11:

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 12:

Class : Class 5
nope

Ans 13:

Class : Class 6

Ans 14:

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 15:

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 16:

Class : Class 8
0 is the answer

Ans 17:

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 18:

Class : Class 5
you guys are right

Ans 19:

Class : Class 5
This SOF is bad and mad

Ans 20:

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

Ans 21:

Class : Class 5

Ans 22:

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

Ans 23:

Class : Class 5
Anwer is C. 1 is a factor of every number and not the multiple

Ans 24:

Class : Class 5
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 25:

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

Ans 26:

Class : Class 7

Ans 27:

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 28:

Class : Class 6
The answer is C.

Ans 29:

Class : Class 7
the correct answer should be option c.

Ans 30:

Class : Class 5
C

Ans 31:

Class : Class 3
1 is a factor of all natural numbers .It is not multiple of all numbers

Ans 32:

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 33:

Class : Class 5
maybe a.

Ans 34:

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

Ans 35:

Class : Class 8
nope

Ans 36:

Class : Class 5
The correct answer is C

Ans 37:

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 38:

Class : Class 5
wrong ans shown

Ans 39:

Class : Class 3
The answer is C

Ans 40:

Class : Class 6
The answer is wrongly given at the back . It should be C

Ans 41:

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

Ans 42:

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 43:

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.

Ans 44:

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 45:

Class : Class 4
1X0 IS 0.2XO 03X0 0easy peasy.

Ans 46:

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 47:

Class : Class 5
ccccccccccccccccccccccccccccccccccccccc

Ans 48:

Class : Class 5
it should be c as their is no number that is the multiple of every number

Ans 49:

Class : Class 5
the correct answer is C

Ans 50:

Class : Class 7
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 51:

Class : Class 7
the answer is c because 0 is a natural number and 1 is the only multiple of itself

Ans 52:

Class : Class 6
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
It should be d . Please tell us master admin

Ans 54:

Class : Class 4
The answer should be C

Ans 55:

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

Ans 56:

Class : Class 5
Maybe c

Ans 57:

Class : Class 5
ans B if you don't know then scratch your brain

Ans 58:

Class : Class 5
sure it is C

Ans 59:

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 60:

Class : Class 6
the answer is c

Ans 61:

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 62:

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

Ans 63:

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 64:

Class : Class 5
0 is the answer

Ans 65:

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 66:

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 67:

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 68:

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 69:

Class : Class 5
answer is c

Ans 70:

Class : Class 8
0 is the answer

Ans 71:

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

Ans 72:

Class : Class 8
Answer will be 0 because 2*0=0,5653453*0=0,4765868756733465358678757646535436536854786*0=0

Ans 73:

Class : Class 5
FACTOR OF EVERY NUMBER IS 1!!!!!!!!!!!!!!!!!!!!!!!!!!! 1 IS NOT THE MULTIPLE OF EVERY NUMBER!!!!!!!!!!!!!!!!!!!!!!

Ans 74:

Class : Class 5
it should be C not B

Ans 75:

Class : Class 5
it may be c or d

Ans 76:

Class : Class 5
I mean ans is c

Ans 77:

Class : Class 5

Ans 78:

Class : Class 6
c

Ans 79:

Class : Class 6

Ans 80:

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 81:

Class : Class 6
C is the correct answer

Ans 82:

Class : Class 5
The correct answer is C

Ans 83:

Class : Class 7
nope!

Ans 84:

Class : Class 3

Ans 85:

Class : Class 5
The correct answer is C

Ans 86:

Class : Class 5

Ans 87:

Class : Class 1
Whoever wrote a or b is foolish. C is the answer.

Ans 88:

Class : Class 5
c

Ans 89:

Class : Class 6
The answer is C.

Ans 90:

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 91:

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 92:

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

Ans 93:

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 94:

Class : Class 8
0 is the answer

Ans 95:

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 96:

Class : Class 8
the smallest multiple of a number is itself

Ans 97:

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

Ans 98:

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 99:

Class : Class 6
The question is wrong. It should be: The natural number which is a factor of every number.

Ans 100:

Class : Class 2
the answer is c

Ans 101:

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 102:

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 103:

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 104:
