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

Ans 2:

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 3:

Class : Class 6
the correct answer is C

Ans 4:

Class : Class 7
C

Ans 5:

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 6:

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 7:

Class : Class 7
maybe a.

Ans 8:

Class : Class 5
This SOF is bad and mad

Ans 9:

Class : Class 5

Ans 10:

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

Ans 11:

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

Ans 12:

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 13:

Class : Class 8
you guys are right

Ans 14:

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 15:

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 16:

Class : Class 6
it should be C not B

Ans 17:

Class : Class 5
And.will C

Ans 18:

Class : Class 1
(C) (C) (C) (C) (C) IS CORRECT

Ans 19:

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 20:

Class : Class 2
the answer is c

Ans 21:

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

Ans 22:

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 23:

Class : Class 6
There is no such number.

Ans 24:

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 25:

Class : Class 4
1 is the factor of every number not multiple he should learn.

Ans 26:

Class : Class 5
the ans: is c not b

Ans 27:

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 28:

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

Ans 29:

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

Ans 30:

Class : Class 7
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 31:

Class : Class 6
ccccccccccccccccccccccccccccccccccccccc

Ans 32:

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

Ans 33:

Class : Class 8

Ans 34:

Class : Class 6
0 is the answer

Ans 35:

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 36:

Class : Class 3
The answer is C

Ans 37:

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

Ans 38:

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

Ans 39:

Class : Class 8
The answer is C.

Ans 40:

Class : Class 1
every number multiplyied by 0 is 0 so its (A)

Ans 41:

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 42:

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 43:

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

Ans 44:

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 45:

Class : Class 6

Ans 46:

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

Ans 47:

Class : Class 6
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 48:

Class : Class 7
The correct answer is C

Ans 49:

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 50:

Class : Class 10
nope

Ans 51:

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 52:

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 53:

Class : Class 7
Anwer is C. 1 is a factor of every number and not the multiple

Ans 54:

Class : Class 5
Maybe c

Ans 55:

Class : Class 5

Ans 56:

Class : Class 5
definitely the answer is c

Ans 57:

Class : Class 5
c

Ans 58:

Class : Class 9
nope!

Ans 59:

Class : Class 6
the answer is c

Ans 60:

Class : Class 6
foolish

Ans 61:

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

Ans 62:

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

Ans 63:

Class : Class 6
The answer should be C.

Ans 64:

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

Ans 65:

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 66:

Class : Class 7
yes the answer is wrong on the SOF portal . It is showing answer B but the correct answer is C

Ans 67:

Class : Class 3

Ans 68:

Class : Class 5
I mean ans is c

Ans 69:

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 70:

Class : Class 4
c is the ans.

Ans 71:

Class : Class 5
stupid it is C

Ans 72:

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 73:

Class : Class 8
it may be c or d

Ans 74:

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

Ans 75:

Class : Class 7
CORRECT ANSWER IS D BECAUSE THE BECAUSE THE SMALLEST MULTIPLE OF A NUMBER IS THE NUMBER ITSELF.

Ans 76:

Class : Class 7
i think it should be c

Ans 77:

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 78:

Class : Class 8
0 is the answer

Ans 79:

Class : Class 7
The correct answer is C

Ans 80:

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

Ans 81:

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 82:

Class : Class 5
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 83:

Class : Class 5
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 84:

Class : Class 7

Ans 85:

Class : Class 6
0 is not a natural number

Ans 86:

Class : Class 10
0 is the answer

Ans 87:

Class : Class 5
nope

Ans 88:

Class : Class 5
REeeeeeeeeeeee

Ans 89:

Class : Class 6

Ans 90:

Class : Class 5
answer is c

Ans 91:

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

Ans 92:

Class : Class 5

Ans 93:

Class : Class 4
The answer should be C

Ans 94:

Class : Class 6
The answer is C.

Ans 95:

Class : Class 7
the correct answer is c

Ans 96:

Class : Class 5
sure it is C

Ans 97:

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 98:

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 99:

Class : Class 5
This is impossible how can a multiple of every number be 1!!!!

Ans 100:

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

Ans 101:

Class : Class 6
it should be c as their is no number that is the multiple of every number

Ans 102:
