0 is the answer

Ans 2:

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 3:

Class : Class 6
ccccccccccccccccccccccccccccccccccccccc

Ans 4:

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 5:

Class : Class 10
The answer is C.

Ans 6:

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

Ans 7:

Class : Class 5
Maybe c

Ans 8:

Class : Class 6
0 is not a natural number

Ans 9:

Class : Class 5
answer is c

Ans 10:

Class : Class 8
The question is wrong. It should be: The natural number which is a factor of every number.

Ans 11:

Class : Class 3

Ans 12:

Class : Class 7
This is impossible how can a multiple of every number be 1!!!!

Ans 13:

Class : Class 7
i think it should be c

Ans 14:

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

Ans 15:

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 16:

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 17:

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 18:

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 19:

Class : Class 9
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 20:

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 21:

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

Ans 22:

Class : Class 7
The correct answer is C

Ans 23:

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 24:

Class : Class 6

Ans 25:

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 26:

Class : Class 5
And.will C

Ans 27:

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

Ans 28:

Class : Class 6

Ans 29:

Class : Class 3
The answer is C

Ans 30:

Class : Class 9
c

Ans 31:

Class : Class 9
yes the answer is wrong on the SOF portal . It is showing answer B but the correct answer is C

Ans 32:

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

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.

Ans 34:

Class : Class 7
C

Ans 35:

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 36:

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 37:

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

Ans 38:

Class : Class 5
sure it is C

Ans 39:

Class : Class 8
0 is the answer

Ans 40:

Class : Class 9
MY FIRST COMMENT WAS WRONG ... I WANTED TO WRITE -THE WHOLE NUMBER THAT IS THE FACTOR OF EVERY NUMBER IS _______.

Ans 41:

Class : Class 6

Ans 42:

Class : Class 9
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 43:

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

Ans 44:

Class : Class 4
nope!

Ans 45:

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

Ans 46:

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

Ans 47:

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

Ans 48:

Class : Class 5

Ans 49:

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 50:

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 51:

Class : Class 6
FACTOR OF EVERY NUMBER IS 1!!!!!!!!!!!!!!!!!!!!!!!!!!! 1 IS NOT THE MULTIPLE OF EVERY NUMBER!!!!!!!!!!!!!!!!!!!!!!

Ans 52:

Class : Class 6
the answer is c

Ans 53:

Class : Class 10
0 is the answer

Ans 54:

Class : Class 6
There is no such number.

Ans 55:

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 56:

Class : Class 8
the correct answer should be option c.

Ans 57:

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

Ans 58:

Class : Class 8

Ans 59:

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

Ans 60:

Class : Class 6

Ans 61:

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 62:

Class : Class 7
the correct answer is c

Ans 63:

Class : Class 6
foolish

Ans 64:

Class : Class 9

Ans 65:

Class : Class 4
The answer should be C

Ans 66:

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 67:

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 68:

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

Ans 69:

Class : Class 6
Hi guys the answer should be c. Some people say its 0 but 0 is not a natural number.

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 5
THE ANS IS that there is no such number

Ans 72:

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 73:

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

Ans 74:

Class : Class 9
it should be c as their is no number that is the multiple of every number

Ans 75:

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 76:

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 77:

Class : Class 8
C

Ans 78:

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

Ans 79:

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

Ans 80:

Class : Class 5
The correct answer is C

Ans 81:

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 82:

Class : Class 9
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 83:

Class : Class 5

Ans 84:

Class : Class 6
1 is the factor of every number not a multiple.The answer should be (A)

Ans 85:

Class : Class 6
the correct answer is C

Ans 86:

Class : Class 8
CORRECT ANSWER IS D BECAUSE THE BECAUSE THE SMALLEST MULTIPLE OF A NUMBER IS THE NUMBER ITSELF.

Ans 87:

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

Ans 88:

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 89:

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

Ans 90:

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

Ans 91:

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 92:

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 93:

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 94:

Class : Class 8
I agree

Ans 95:

Class : Class 6

Ans 97:

Class : Class 9

Ans 98:

Class : Class 2
the answer is c

Ans 99:

Class : Class 8
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 100:

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 101:

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

Ans 102:

Class : Class 8
it may be c or d

Ans 103:

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 104:

Class : Class 5

Ans 105:

Class : Class 4
The answer should be C.

Ans 106:

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 107:

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 108:

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

Ans 109:

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 110:

Class : Class 9
wrong ans shown

Ans 111:

Class : Class 6
The answer is C.

Ans 112:

Class : Class 6
it should be C not B

Ans 113:

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

Ans 114:

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 115:

Class : Class 6
C is the correct answer

Ans 116:

Class : Class 8
C is the answer. I don’t understand how 1 can come.

Ans 117:

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 118:

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

Ans 119:

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

Ans 120:

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

Ans 121:

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 122:

Class : Class 6

Ans 123:

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

Ans 124:

Class : Class 5
stupid it is C

Ans 125:

Class : Class 8
you guys are right

Ans 126:

Class : Class 5
This SOF is bad and mad

Ans 127:

Class : Class 5
REeeeeeeeeeeee

Ans 128:

Class : Class 6
c is the ans.

Ans 129:

Class : Class 9
Anwer is C. 1 is a factor of every number and not the multiple

Ans 130:

Class : Class 7
The correct answer is C

Ans 131:

Class : Class 8
0 is the answer

Ans 132:

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

Ans 133:

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 134:

Class : Class 5
definitely the answer is c

Ans 135:

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

Ans 136:

Class : Class 5
c

Ans 137:

Class : Class 8
0 is the only answer

Ans 138:

Class : Class 7
the ans: is c not b

Ans 139:

Class : Class 10
nope

Ans 140:

Class : Class 9
maybe a.

Ans 141:

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 142:

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
