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.

adwitiya saxena from Ryan Internatinational School, Navi Mumbai
Class : Class 6

Ans 10:

Student from School, City
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 11:

Bhabani Prasad from Narayan School, Kolkata
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.

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

Ans 16:

Aagnik Ray from St. Xavier's Collegiate School, Kolkata
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 17:

Advika Narkar from The Shishukunj International School, Jhalaria Campus, Indore
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:

Shweta Garg from Vibgyor high, Vadodara
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 31:

Amyra Chopra from Ivy World School Jalandhar, Jalandhar
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 32:

Vaikhari Sonawane from symbiosis school, Nashik
Class : Class 10
the smallest multiple of a number is itself

Ans 33:

Navya Saini from dpsnoida, Noida
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 34:

AYAAN.MUSTAFA from Dps noida, Noida
Class : Class 5
Maybe c

Ans 35:

Tashvee Sahoo from NPS International, Singapore
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 36:

DAIVIK AMBATI from Kendriya Vidyalaya, Dharwad, Dharwad
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 37:

Adarsh from DPS, Raipur
Class : Class 5
The correct answer is C. There is no such number.

Ans 38:

Aarush Thakur from DPS, Gurgaon
Class : Class 6
The answer is wrongly given at the back . It should be C

Ans 39:

Rishik De Sarkar from Delhi Public School Gurgaon, Gurgaon
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"

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?
