The natural number which is a multiple of every number is ______.
A 0
B 1
C There is no such number
D None of these
answer must be c
Ans 1:
Class : Class 6
This is impossible 1 is a factor of every number not a multiple
Ans 2:
Class : Class 9
the answer is c because 0 is a natural number and 1 is the only multiple of itself
Ans 3:
Class : Class 6
the ans: is c not b
Ans 4:
Class : Class 5
c
Ans 5:
Class : Class 7
0 is the answer
Ans 6:
Class : Class 5
Ans 7:
Class : Class 7
C is the answer. I don’t understand how 1 can come.
Ans 8:
Class : Class 10
the smallest multiple of a number is itself
Ans 9:
Class : Class 8
0 is the answer
Ans 10:
Class : Class 8
you guys are right
Ans 11:
Class : Class 6
Hi guys the answer should be c. Some people say its 0 but 0 is not a natural number.
Ans 12:
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 13:
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 14:
Class : Class 4
The answer should be C
Ans 15:
Class : Class 3
Ans 16:
Class : Class 3
The answer should be C.
Ans 17:
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 18:
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 19:
Class : Class 9
maybe a.
Ans 20:
Class : Class 3
1 is a factor of all natural numbers .It is not multiple of all numbers
Ans 21:
Class : Class 5
I mean ans is c
Ans 22:
Class : Class 6
C is the correct answer
Ans 23:
Class : Class 6
ccccccccccccccccccccccccccccccccccccccc
Ans 24:
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 25:
Class : Class 8
0 is the answer
Ans 26:
Class : Class 8
the correct answer should be option c.
Ans 27:
Class : Class 9
c
Ans 28:
Class : Class 8
MY FIRST COMMENT WAS WRONG ... I WANTED TO WRITE -THE WHOLE NUMBER THAT IS THE FACTOR OF EVERY NUMBER IS _______.
Ans 29:
Class : Class 4
nope!
Ans 30:
Class : Class 8
it may be c or d
Ans 31:
Class : Class 5
Ans 32:
Class : Class 6
The answer is wrongly given at the back .
It should be C
Ans 33:
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 34:
Class : Class 5
This SOF is bad and mad
Ans 35:
Class : Class 7
zero is not a natural number, so A is incorrect. The correct answer must be D
Ans 36:
Class : Class 5
sure it is C
Ans 37:
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 38:
Class : Class 5
MASTER ANSWER !!!!!!!!!!!!! ANS IS C.......... .
Ans 39:
Class : Class 10
nope
Ans 40:
Class : Class 5
the question is the wrongthe correct option is cand the smallest multiple of every number is the number it itself
Ans 41:
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 42:
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 43:
Class : Class 7
The correct answer is C
Ans 44:
Class : Class 6
0 is not a natural number
Ans 45:
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 46:
Class : Class 6
the correct answer is C
Ans 47:
Class : Class 7
1 is the factor of every number not multiple he should learn.
Ans 48:
Class : Class 8
Ans 49:
Class : Class 6
Ans 50:
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
Ans 51:
Class : Class 3
The answer is C
Ans 52:
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 53:
Class : Class 6
This is impossible how can a multiple of every number be 1!!!!
Ans 54:
Class : Class 5
Maybe c
Ans 55:
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
Ans 56:
Class : Class 6
Yeah it is c) OMG there are so many comments for this question!!
Ans 57:
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.
Ans 58:
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 59:
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 60:
Class : Class 7
The answer is a because 0 is a natural number and is a multiple of every number. for eg- 19*0
Ans 61:
Class : Class 5
0 is the answer but it is showing 1 as answer. Problem!
Ans 62:
Class : Class 6
Ans 63:
Class : Class 7
C
Ans 64:
Class : Class 5
definitely the answer is c
Ans 65:
Class : Class 6
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 66:
Class : Class 10
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 67:
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 68:
Class : Class 7
(C) (C) (C) (C) (C) IS CORRECT
Ans 69:
Class : Class 6
Answer should be corrected, 1 is factor of any number, but not multiple of every number. Correct answer is C.
Ans 70:
Class : Class 5
answer is c as 0 is not a natural number and 1 is a factor of every number,not multiple
Ans 71:
Class : Class 6
It should be c. There is no such number. And 1 is factor not multiple!!!
Ans 72:
Class : Class 8
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 73:
Class : Class 9
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 74:
Class : Class 5
THE ANS IS that there is no such number
Ans 75:
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 76:
Class : Class 5
It should be d . Please tell us master admin
Ans 77:
Class : Class 2
Whoever wrote a or b is foolish. C is the answer.
Ans 78:
Class : Class 6
1 is the factor of every number not a multiple.The answer should be (A)
Ans 79:
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 ?????
Ans 80:
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.
Ans 81:
Class : Class 8
The answer is C because 1 is the factor of every number, not the multiple. And 0 is the multiple of every number but it is not a natural number
Ans 82:
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.
Ans 83:
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 84:
Class : Class 5
The answer is C. One is not a multiple of every number
Ans 85:
Class : Class 8
Ans 86:
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 87:
Class : Class 5

every number multiplyied by 0 is 0 so its (A)
Ans 95:
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 96:
Class : Class 5
ans B if you don't know then scratch your brain
Ans 97:
Class : Class 7
i think it should be c
Ans 98:
Class : Class 7
The correct answer is C
Ans 99:
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.
Ans 100:
Class : Class 5
answer is c
Ans 101:
Class : Class 6
Answer is D. 1 is not a multiple but factor of all natural numbers.
Ans 102:
Class : Class 7
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 103:
Class : Class 8
yes the answer is wrong on the SOF portal . It is showing answer B but the correct answer is C
Ans 104:
Class : Class 7
I agree
Ans 105:
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 106:
Class : Class 8
Ans 107:
Class : Class 6
THERE IS NO SUCH NUMBER. THE SMALLEST MULTIPLE OF A NUMBER IS THE NUMBER IT SELF.
Ans 108:
Class : Class 8
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 109:
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 110:
Class : Class 5
The correct answer is C. There is no such number.
Ans 111:

souvagya saha from de nobili fri dhanbad1is a factor of every number. the answer is c.
Ans 115:
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 116:
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 117:
Class : Class 2
the answer is c
Ans 118:
Class : Class 6
There is no such number.
Ans 119:
Class : Class 6
it should be c as their is no number that is the multiple of every number

wrong ans shown
Ans 126:
Class : Class 6
it should be C not B
Ans 127:
Class : Class 8
0 is the only answer
Ans 128:
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 129:
Class : Class 6
Ans is because 0 is not a natural number and 1 is a factor of every number not a multiple
Ans 130:
Class : Class 5
c is the ans.
Ans 131:
Class : Class 9
The answer is C.
Ans 132:
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 133:
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 134:
Class : Class 8
CORRECT ANSWER IS D BECAUSE THE BECAUSE THE SMALLEST MULTIPLE OF A NUMBER IS THE NUMBER ITSELF.
Ans 135:
Class : Class 5
0 is the answer
Ans 136:
Class : Class 10
0 is the answer
Ans 137:
Class : Class 8
Answer will be 0 because 2*0=0,5653453*0=0,4765868756733465358678757646535436536854786*0=0
Ans 138:
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 139:
Class : Class 5
it must be c as 1 is the factor of every number not multiple!
Ans 140:
Class : Class 6
FACTOR OF EVERY NUMBER IS 1!!!!!!!!!!!!!!!!!!!!!!!!!!! 1 IS NOT THE MULTIPLE OF EVERY NUMBER!!!!!!!!!!!!!!!!!!!!!!
Ans 141:
Class : Class 6
Ans 142:
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 143:
Class : Class 6
The answer is C.
Ans 144:
Class : Class 6
the answer is obviously C because 0 is the only number which is it but it is a whole number
Ans 145:
Class : Class 5
The question is wrong....1 can be factor of all natural numbers not the multiple
