c

Ans 11:

Class : Class 4
The answer should be C

Ans 12:

Class : Class 7

Ans 13:

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 14:

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 15:

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

Ans 16:

Class : Class 4
The answer should be C.

Ans 17:

Ans 21:

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

Ans 22:

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 23:

Class : Class 5

Ans 24:

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 25:

Class : Class 5
the correct answer is C

Ans 26:

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

Ans 27:

Class : Class 5
0 is the answer

Ans 28:

Class : Class 6
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 29:

Class : Class 5
c

Ans 30:

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 31:

Class : Class 6

Ans 32:

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 33:

Class : Class 7
the smallest multiple of a number is itself

Ans 34:

Class : Class 6
The answer is C.

Ans 35:

Class : Class 3
The answer is C

Ans 36:

Class : Class 5

Ans 37:

Class : Class 5
it may be c or d

Ans 38:

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

Ans 39:

Class : Class 8
nope

Ans 40:

Class : Class 1

Ans 41:

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 42:

Class : Class 6
souvagya saha from de nobili fri dhanbad1is a factor of every number. the answer is c.

Ans 43:

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

Ans 44:

Class : Class 5
The correct answer is C

Ans 45:

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

Ans 46:

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 47:

Class : Class 7
the correct answer is c

Ans 48:

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 49:

Class : Class 6

Ans 50:

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

Ans 51:

Class : Class 6

Ans 52:

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 53:

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 54:

Class : Class 6
foolish

Ans 55:

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

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 8
0 is the answer

Ans 58:

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

Ans 59:

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 60:

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

Ans 61:

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 62:

Class : Class 6
0 is the only answer

Ans 63:

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 64:

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

Ans 65:

Class : Class 5
maybe a.

Ans 66:

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 67:

Class : Class 5
you guys are right

Ans 68:

Class : Class 6
0 is not a natural number

Ans 69:

Class : Class 2
the answer is c

Ans 70:

Class : Class 5
answer is c

Ans 71:

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 72:

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

Ans 73:

Class : Class 5

Ans 74:

Class : Class 5
c is the ans.

Ans 75:

Class : Class 5
nope

Ans 76:

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

Ans 77:

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 78:

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

Ans 79:

Class : Class 7
nope!

Ans 80:

Class : Class 6
There is no such number.

Ans 81:

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

Ans 82:

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

Ans 83:

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 84:

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 85:

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

Ans 86:

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

Ans 87:

Class : Class 6
The answer is C.

Ans 88:

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 89:

Class : Class 6
C is the correct answer

Ans 90:

Class : Class 8
0 is the answer

Ans 91:

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 92:

Class : Class 5
I mean ans is c

Ans 93:

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 94:

Class : Class 5
ccccccccccccccccccccccccccccccccccccccc

Ans 95:

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 96:

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 97:

Class : Class 5
The correct answer is C

Ans 98:

Class : Class 6
the answer is c

Ans 99:

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 100:

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

Ans 101:

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

Ans 102:

Class : Class 5
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 .
