MASTER ANSWER !!!!!!!!!!!!! ANS IS C.......... .

Ans 4:

Class : Class 5
it may be c or d

Ans 5:

Class : Class 7
MY FIRST COMMENT WAS WRONG ... I WANTED TO WRITE -THE WHOLE NUMBER THAT IS THE FACTOR OF EVERY NUMBER IS _______.

Ans 6:

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 7:

Class : Class 4
1 is the factor of every number not a multiple.The answer should be (A)

Ans 8:

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 9:

Class : Class 6

Ans 10:

Class : Class 8
0 is the answer

Ans 11:

Class : Class 8
you guys are right

Ans 12:

Class : Class 6
The question is wrong. It should be: The natural number which is a factor of every number.

Ans 13:

Class : Class 5
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 14:

Class : Class 8
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 15:

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

Ans 16:

Class : Class 5
nope

Ans 17:

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 18:

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

Ans 19:

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 20:

Class : Class 7
the correct answer should be option c.

Ans 21:

Class : Class 7
the answer is c because 0 is a natural number and 1 is the only multiple of itself

Ans 22:

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

Ans 23:

Class : Class 5
it should be c as their is no number that is the multiple of every number

Ans 24:

Class : Class 5
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 25:

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

Ans 26:

Class : Class 3

Ans 27:

Class : Class 5
yes the answer is wrong on the SOF portal . It is showing answer B but the correct answer is C

Ans 28:

Class : Class 5
c is the ans.

Ans 29:

Class : Class 8
nope

Ans 30:

Class : Class 5
i think it should be c

Ans 31:

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 32:

Class : Class 5
The correct answer is C

Ans 33:

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 34:

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

Ans 35:

Class : Class 5
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 36:

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 37:

Class : Class 5
The correct answer is C

Ans 38:

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 39:

Class : Class 5
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 40:

Class : Class 3
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 41:

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 42:

Class : Class 6
The answer is C.

Ans 43:

Class : Class 5
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 44:

Class : Class 5
sure it is C

Ans 45:

Class : Class 5
This SOF is bad and mad

Ans 46:

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

Ans 47:

Class : Class 3
The answer is C

Ans 48:

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 49:

Class : Class 7
nope!

Ans 50:

Class : Class 5
it should be C not B

Ans 51:

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 52:

Class : Class 6
The answer is C.

Ans 53:

Class : Class 5
c

Ans 54:

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 55:

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

Ans 56:

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 57:

Class : Class 2
the answer is c

Ans 58:

Class : Class 5
wrong ans shown

Ans 59:

Class : Class 5
maybe a.

Ans 60:

Class : Class 6
the answer is c

Ans 61:

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

Ans 62:

Class : Class 5
Maybe c

Ans 63:

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

Ans 64:

Class : Class 1
Whoever wrote a or b is foolish. C is the answer.

Ans 65:

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

Ans 66:

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 67:

Class : Class 5
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 68:

Class : Class 5
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 69:

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 70:

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

Ans 71:

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

Ans 72:

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

Ans 73:

Class : Class 6
c

Ans 74:

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

Ans 75:

Class : Class 5
answer is c

Ans 76:

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 77:

Class : Class 5
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 78:

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 79:

Class : Class 6

Ans 80:

Class : Class 5
I mean ans is c

Ans 81:

Class : Class 5
The answer is a because 0 is a natural number and is a multiple of every number. for eg- 19*0

Ans 82:

Class : Class 6
The answer should be C.

Ans 83:

Class : Class 6
C is the correct answer

Ans 84:

Class : Class 5
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 5

Ans 86:

Class : Class 8
0 is the answer

Ans 87:

Class : Class 7

There is no such number.

Ans 90:

Class : Class 5

Ans 91:

Class : Class 6
0 is the only answer

Ans 92:

Class : Class 5
Anwer is C. 1 is a factor of every number and not the multiple

Ans 93:

Class : Class 4
The answer should be C

Ans 94:

Class : Class 6
0 is not a natural number

Ans 95:

Class : Class 7
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 96:

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

Ans 97:

Class : Class 5
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 98:

Class : Class 5
the correct answer is C
