Class : Class 6

Ans 3:

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 4:

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

Ans 5:

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

Ans 6:

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 7:

Class : Class 4
The answer should be C.

Ans 8:

Class : Class 7
i think it should be c

Ans 9:

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

Ans 10:

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

Ans 11:

Class : Class 5
definitely the answer is c

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 .

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

Ans 17:

Class : Class 6
the answer is c

Ans 18:

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 19:

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 20:

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 21:

Class : Class 7
the correct answer is c

Ans 22:

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 23:

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

Ans 24:

Class : Class 10
The answer is C.

Ans 25:

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 26:

Class : Class 4
The answer should be C

Ans 27:

Class : Class 6
The answer is C.

Ans 28:

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 29:

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

Kavya Vikas Gatkal from Podar International School JalnaThe answer is c because 1 is a factor of every number not a multiple

Ans 32:

Class : Class 7
c is the ans.

Ans 33:

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

Ans 34:

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

Ans 35:

Class : Class 7
The correct answer is C

Ans 36:

Class : Class 5
stupid it is C

Ans 37:

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 38:

Class : Class 5

Ans 39:

Class : Class 5

Ans 40:

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 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 10
wrong ans shown

Ans 43:

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 44:

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

Ans 45:

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 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

Ans 48:

Class : Class 8
you guys are right

Ans 49:

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 50:

Class : Class 5
sure it is C

Ans 51:

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 52:

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 53:

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 54:

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 55:

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

Ans 56:

Class : Class 8
0 is the answer

Ans 57:

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 58:

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

Ans 59:

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

Ans 60:

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

Ans 61:

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

Ans 62:

Class : Class 7
The correct answer is C

Ans 63:

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 64:

Class : Class 5
And.will C

Ans 65:

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

Ans 66:

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 67:

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

Ans 68:

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

Ans 69:

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 70:

Class : Class 10
maybe a.

Ans 71:

Class : Class 4
nope!

Ans 72:

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

Ans 73:

Class : Class 2
the answer is c

Ans 74:

Class : Class 8
I agree

Ans 75:

Class : Class 6
0 is not a natural number

Ans 76:

Class : Class 7
the ans: is c not b

Ans 77:

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 78:

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 79:

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 80:

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 81:

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

Ans 82:

Class : Class 5
c

Ans 83:

Class : Class 5

Ans 84:

Class : Class 6
it should be C not B

Ans 85:

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

Ans 86:

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

Ans 87:

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

Ans 88:

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

Ans 89:

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 90:

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 91:

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 92:

Class : Class 8

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 9
c

Ans 95:

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

Ans 96:

Class : Class 8
0 is the answer

Ans 97:

Class : Class 7
1 is the factor of every number not multiple he should learn.

Ans 98:

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 105:

Class : Class 7
C

Ans 106:

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

Ans 107:

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 108:

Class : Class 8
0 is the only answer

Ans 109:

Class : Class 6
the correct answer is C

Ans 110:

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 111:

Class : Class 10
nope

Ans 112:

Class : Class 6

Class : Class 6

Ans 115:

Class : Class 6

Ans 116:

Class : Class 10
0 is the answer

Ans 117:

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 118:

Class : Class 6
foolish

Ans 119:

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

Ans 120:

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

Ans 121:

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

Ans 122:

Class : Class 8
0 is the answer

Ans 123:

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 124:

Class : Class 5
REeeeeeeeeeeee

Ans 125:

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 126:

Class : Class 5
The correct answer is C

Ans 127:

Class : Class 9
MY FIRST COMMENT WAS WRONG ... I WANTED TO WRITE -THE WHOLE NUMBER THAT IS THE FACTOR OF EVERY NUMBER IS _______.

Ans 128:

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 129:

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 130:

Class : Class 5
0 is the answer

Ans 131:

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 132:

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

Ans 133:

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

Ans 134:

Class : Class 5
answer is c

Ans 135:

Class : Class 6
There is no such number.

Ans 136:

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

Ans 137:

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

Ans 138:

Class : Class 3
The answer is C

Ans 139:

Class : Class 5
Maybe c

Ans 140:

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