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

Ans 2:

Class : Class 4
nope!

Ans 3:

Class : Class 8
0 is the answer

Ans 4:

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 5:

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

Ans 6:

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 7:

Class : Class 7
the correct answer is c

Ans 8:

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 9:

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

Ans 10:

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 11:

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 12:

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

Ans 13:

Class : Class 8
I agree

Ans 14:

Class : Class 7
The correct answer is C

Ans 15:

Class : Class 9
maybe a.

Ans 16:

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

Ans 17:

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

Ans 18:

Class : Class 10
0 is the answer

Ans 19:

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 20:

Class : Class 8
0 is the only answer

Ans 21:

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 22:

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 23:

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

Ans 24:

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 25:

Class : Class 7
C

Ans 26:

Class : Class 5

Ans 27:

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 28:

Class : Class 5
I mean ans is c

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

Ans 31:

Class : Class 6
it should be C not B

Ans 32:

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 33:

Class : Class 5
Maybe c

Ans 34:

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 35:

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

Ans 36:

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

Ans 37:

Ans 38:

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

Ans 43:

Class : Class 5
sure it is C

Ans 44:

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 45:

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

Ans 46:

Class : Class 6

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.

Ans 48:

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

Ans 49:

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

Ans 50:

Class : Class 3

Ans 51:

Class : Class 5
stupid it is C

Ans 52:

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 53:

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 54:

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 55:

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

Ans 56:

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 57:

Class : Class 5
c

Ans 58:

Class : Class 8
0 is the answer

Ans 59:

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

Ans 60:

Class : Class 9
c

Ans 61:

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 62:

Class : Class 10
nope

Ans 63:

Class : Class 10
The answer is C.

Ans 64:

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 65:

Class : Class 8
you guys are right

Ans 66:

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

Ans 67:

Class : Class 6
There is no such number.

Ans 68:

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

Ans 69:

Class : Class 8
C

Ans 70:

Class : Class 7
the ans: is c not b

Ans 71:

Class : Class 6
the answer is c

Ans 72:

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

Ans 73:

Class : Class 7
i think it should be c

Ans 74:

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

Ans 75:

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

Ans 76:

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

Ans 77:

Class : Class 6
The answer is C.

Ans 78:

Class : Class 6
C is the correct answer

Ans 79:

Class : Class 6
ccccccccccccccccccccccccccccccccccccccc

Ans 80:

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

Ans 81:

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

Ans 82:

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 83:

Class : Class 5
REeeeeeeeeeeee

Ans 84:

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 85:

Class : Class 6
the correct answer is C

Ans 86:

Class : Class 6

Ans 88:

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

Ans 89:

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 90:

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

Ans 91:

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

Ans 92:

Class : Class 8

Ans 93:

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 94:

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

Ans 95:

Class : Class 6
foolish

Ans 96:

Class : Class 6

Ans 97:

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 98:

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

Ans 99:

Class : Class 5
answer is c

Ans 100:

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 101:

Class : Class 9

Ans 102:

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

Ans 103:

Class : Class 2
the answer is c

Ans 104:

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 105:

Class : Class 6

Ans 106:

Class : Class 5
And.will C

Ans 107:

Class : Class 8
0 is the answer

Ans 108:

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

Ans 109:

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 110:

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

Ans 111:

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

Ans 112:

Class : Class 6
c is the ans.

Ans 113:

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 114:

Class : Class 5
0 is the answer

Ans 115:

Class : Class 4
The answer should be C

Ans 116:

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 117:

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

Ans 118:

Class : Class 9
wrong ans shown

Ans 119:

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 120:

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 121:

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 122:

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 123:

Class : Class 5
definitely the answer is c

Ans 124:

Class : Class 6
0 is not a natural number

Ans 125:

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

Ans 126:

Class : Class 7

Ans 127:

Class : Class 5
This SOF is bad and mad

Ans 128:

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

Ans 129:

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

Ans 130:

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 131:

Class : Class 5
nope

Ans 132:

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 133:

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 134:

Class : Class 9

Ans 135:

Class : Class 5
The correct answer is C

Ans 136:

Class : Class 10
souvagya saha from de nobili fri dhanbad1is a factor of every number. the answer is c.

Ans 137:

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 138:

Class : Class 4
The answer should be C.

Ans 139:

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

Ans 140:

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

Ans 141:

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 142:

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

Ans 143:

Class : Class 3
The answer is C

Ans 144:

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
