The answer is C

Ans 2:

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 3:

Class : Class 7
c is the ans.

Ans 4:

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 5:

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

Ans 6:

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

Ans 7:

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

Ans 8:

Class : Class 2
the answer is c

Ans 9:

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

Ans 10:

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 11:

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

Ans 12:

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 13:

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

Ans 14:

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

Ans 15:

Class : Class 8
This is impossible how can a multiple of every number be 1!!!!

Ans 16:

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 17:

Class : Class 10
yes the answer is wrong on the SOF portal . It is showing answer B but the correct answer is C

Ans 18:

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

Ans 19:

Class : Class 5
I mean ans is c

Ans 20:

Class : Class 7
The correct answer is C

Ans 21:

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

Ans 22:

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 23:

Class : Class 5
stupid it is C

Ans 24:

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 25:

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 26:

Class : Class 6

Ans 27:

Class : Class 10
nope

Ans 28:

Class : Class 6
0 is not a natural number

Ans 29:

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

Ans 30:

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

Ans 31:

Class : Class 5
nope

Ans 32:

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 33:

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

Ans 34:

Class : Class 5
c

Ans 35:

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 36:

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 37:

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 38:

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 39:

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 40:

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

Ans 41:

Class : Class 6

Ans 42:

Class : Class 6
foolish

Ans 43:

Class : Class 8
0 is the answer

Ans 44:

Class : Class 5
And.will C

Ans 45:

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 46:

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

Ans 47:

Class : Class 5

The correct answer is C

Ans 49:

Class : Class 5

Ans 50:

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

Ans 52:

Class : Class 5
answer is c

Ans 53:

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

Ans 54:

Class : Class 8

Ans 55:

Class : Class 5
definitely the answer is c

Ans 56:

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 57:

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

Ans 58:

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 59:

Class : Class 7
The correct answer is C

Ans 60:

Class : Class 5

Ans 61:

Class : Class 5
Maybe c

Ans 62:

Class : Class 6
ccccccccccccccccccccccccccccccccccccccc

Ans 63:

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 64:

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

Ans 65:

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 66:

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 67:

Class : Class 8
0 is the only answer

Ans 68:

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 69:

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 70:

Class : Class 9
I agree

Ans 71:

Class : Class 7
C

Ans 72:

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 73:

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

Ans 74:

Class : Class 6
it should be C not B

Ans 75:

Class : Class 5
0 is the answer

Ans 76:

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 77:

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 78:

Class : Class 10
Anwer is C. 1 is a factor of every number and not the multiple

Ans 79:

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

Ans 80:

Class : Class 4
The answer should be C

Ans 81:

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 82:

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

Ans 83:

Class : Class 10
0 is the answer

Ans 84:

Class : Class 8
you guys are right

Ans 85:

Class : Class 10
wrong ans shown

Ans 86:

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 87:

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 88:

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 89:

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

Ans 90:

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 91:

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 92:

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 93:

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 94:

Class : Class 7
the correct answer is c

Ans 95:

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

Class : Class 6

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 142:
