SolutionWe know that the king of the jungle is always a Lion. But it is mentioned that 'Lion' is called 'Tiger'. That means Tiger is the king of the jungle. That means Option D is the right answer.

It is 8, SOF has probably miscounted the number of letters, please correct it.

Ans 67:

Class : Class 4
You guys stop arguing! Its 8 they said BETWEEN R and S so there are only 8 letters. Its only 9 if we count R or S with it

Ans 68:

Class : Class 4
8 is the correct option which is in the option D not B.

Ans 69:

Class : Class 7
In your solution you have given 8 as the ans, but in options you have given ans is B (9). Please correct because it is misleading the candidates.

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 3:

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

Ans 4:

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 5:

Class : Class 5
The correct answer is C

Ans 6:

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

Ans 7:

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 8:

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

Ans 13:

Class : Class 8
0 is the answer

Ans 14:

Class : Class 8
0 is the only answer

Ans 15:

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 16:

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 17:

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 18:

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 19:

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

Ans 20:

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

Ans 21:

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

Ans 22:

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

Ans 23:

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

Ans 24:

Class : Class 4
The answer should be C

Ans 25:

Class : Class 10
maybe a.

Ans 26:

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 27:

Class : Class 7
the correct answer is c

Ans 28:

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

Ans 29:

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 30:

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

Ans 31:

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 32:

Class : Class 8

Ans 33:

Class : Class 10
wrong ans shown

Ans 34:

Class : Class 5
Maybe 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 5
This SOF is bad and mad

Ans 37:

Class : Class 8
I agree

Ans 38:

Class : Class 4
The answer should be C.

Ans 39:

Class : Class 6
it should be C not B

Ans 40:

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 41:

Class : Class 5

Ans 42:

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

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 8
it may be c or d

Ans 45:

Class : Class 10
The answer is C.

Ans 46:

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

Ans 47:

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 48:

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 49:

Class : Class 3
The answer is C

Ans 50:

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

Ans 51:

Class : Class 5
sure it is C

Ans 52:

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 53:

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 54:

Class : Class 9
c

Ans 55:

Class : Class 5
c

Ans 56:

Class : Class 8
you guys are right

Ans 57:

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 58:

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 59:

Class : Class 9
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 60:

Class : Class 7
The correct answer is C

Ans 61:

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

Ans 62:

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

Ans 63:

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

Ans 64:

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

Ans 65:

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 66:

Class : Class 6
There is no such number.

Ans 67:

Class : Class 7
the ans: is c not b

Ans 68:

Class : Class 6

Ans 69:

Class : Class 6
the answer is c

Ans 70:

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 71:

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

Ans 72:

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 73:

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

Ans 74:

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

Ans 75:

Class : Class 6
The answer is C.

Ans 76:

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

Ans 77:

Class : Class 5
nope

Ans 78:

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

Ans 79:

Class : Class 7
c is the ans.

Ans 80:

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 81:

Class : Class 6
the correct answer is C

Ans 82:

Class : Class 10
nope

Ans 83:

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

Ans 84:

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

Ans 85:

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

Ans 86:

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 87:

Class : Class 7
The correct answer is C

Ans 88:

Class : Class 5
0 is the answer

Ans 89:

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 90:

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

Ans 91:

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 92:

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

Ans 93:

Class : Class 9

Ans 94:

Class : Class 3

Ans 95:

Class : Class 8
0 is the answer

Ans 96:

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 97:

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 98:

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

Ans 99:

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 100:

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 101:

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

Ans 102:

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

Ans 103:

Class : Class 5
I mean ans is c

Ans 104:

Class : Class 5
definitely the answer is c

Ans 105:

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

Ans 106:

Class : Class 5
MASTER ANSWER !!!!!!!!!!!!! ANS IS C.......... .

Ans 107:

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 108:

Class : Class 10
0 is the answer

Ans 109:

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

Ans 110:

Class : Class 7
C

Ans 111:

Class : Class 7
i think it should be c

Ans 112:

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 113:

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

Ans 114:

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 115:

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 116:

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

Ans 117:

Class : Class 4
nope!

Ans 118:

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 119:

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 120:

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 121:

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

Ans 122:

Class : Class 8
0 is the answer

Ans 123:

Class : Class 9

Ans 124:

Class : Class 2
the answer is c

Ans 125:

Class : Class 5
REeeeeeeeeeeee

Ans 126:

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 140:

Class : Class 6

Ans 141:

Class : Class 5
And.will C

Ans 142:

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

Ans 143:

Class : Class 6

Ans 144:

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 145:

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.
