Ans 62:

Class : Class 8

Ans 1:

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

Ans 2:

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 3:

Class : Class 5
sure it is C

Ans 4:

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 5:

Class : Class 6
There is no such number.

Ans 6:

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

Ans 7:

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

Ans 8:

Class : Class 6
it should be C not B

Ans 9:

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 10:

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 11:

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 12:

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

Ans 13:

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 14:

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 15:

Class : Class 6
foolish

Ans 16:

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

Ans 17:

Class : Class 6
The answer is C.

Ans 18:

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 19:

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

Ans 20:

Class : Class 5
The correct answer is C

Ans 25:

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

Ans 26:

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 27:

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

Ans 28:

Class : Class 5

Ans 29:

Class : Class 6
the answer is c

Ans 30:

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

Ans 31:

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 32:

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 33:

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

Ans 34:

Class : Class 10
The answer is C.

Ans 35:

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 36:

Class : Class 7
c is the ans.

Ans 37:

Class : Class 6

Ans 38:

Class : Class 5
Maybe c

Ans 39:

Class : Class 5
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
the correct answer is C

Ans 42:

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 43:

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 44:

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

Ans 45:

Class : Class 10
0 is the answer

Ans 46:

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 47:

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 48:

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

Ans 49:

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

Ans 50:

Class : Class 6

Ans 51:

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

Ans 52:

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 53:

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

Ans 54:

Class : Class 5
answer is c

Ans 55:

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 56:

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 57:

Class : Class 7
The correct answer is C

Ans 58:

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 59:

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

Ans 60:

Class : Class 8
I agree

Ans 61:

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 62:

Class : Class 5

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
c

Ans 65:

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

Ans 66:

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 67:

Class : Class 9

Ans 68:

Class : Class 5
stupid it is C

Ans 69:

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

Ans 70:

Class : Class 10
nope

Ans 71:

Class : Class 5
I mean ans is c

Ans 72:

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

Ans 73:

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

Ans 74:

Class : Class 6

Ans 75:

Class : Class 5
REeeeeeeeeeeee

Ans 76:

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

Ans 77:

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

Ans 78:

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

Ans 79:

Class : Class 6

Class : Class 6

Ans 86:

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 87:

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

Ans 88:

Class : Class 4
nope!

Ans 89:

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 90:

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

Ans 91:

Class : Class 2
the answer is c

Ans 92:

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 93:

Class : Class 8
0 is the answer

Class : Class 10
maybe a.

Ans 106:

Class : Class 7
The correct answer is C

Ans 107:

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 108:

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

Ans 109:

Ans 110:

Class : Class 3
The answer is C

Ans 111:

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

Ans 112:

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

Ans 113:

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 114:

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 115:

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

Ans 116:

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

Ans 117:

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 118:

Class : Class 9
c

Ans 119:

Class : Class 5
definitely the answer is c

Ans 120:

Class : Class 8
C

Ans 121:

Class : Class 5

Ans 122:

Class : Class 4
The answer should be C

Ans 123:

Class : Class 6
0 is not a natural number

Ans 124:

Class : Class 6
C is the correct answer

Ans 125:

Class : Class 7
C

Ans 126:

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

Ans 127:

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 128:

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 129:

Class : Class 8

Ans 130:

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

Ans 131:

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

Ans 132:

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

Ans 133:

Class : Class 8
0 is the only answer

Ans 134:

Class : Class 5

Ans 135:

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 136:

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

Ans 137:

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 138:

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

Ans 139:

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

Ans 140:

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 141:

Class : Class 10
