The number is 9.
Two number are co-prime if there is no whole number other than 1 that divides them both exactly
163 / 100 No number, other than 1, divides into both numbers, I think.
A prime factor of a number is a prime number that evenly divides the number. A composite number is a number having more factors than just 1 and itself.
Yes. 47 is a prime number because no positive integral number less than 47 apart from 1 divides without remainder into 47.
The number is 9.
Check 9 out.

13 does not divide into 27 so the question makes no sense.
56
2041 is not a prime number. Other than itself and 1, it divides equally into 13 and 157.
13 does not divide exactly into 27 although 27 is divisible by itself. Another number other than 27 that can be divided exactly into 27 is 9.
Yes, it is, since no number other than 1 divides into both to get a whole number
By dividing it by all numbers smaller than itself and if any number divides it exactly with a remainder of '0' then it is a factor. 2 is a prime number and apart from 1 and itself it does not have any factors.
1, because 31 is a prime number, and so there will be no number which divides into it other than 31 and 1.
163 / 100 No number, other than 1, divides into both numbers, I think.
The only prime number that 7 will evenly divide is 7. Any other number that 7 evenly divides will not be prime because it will have more than the exactly two factors (1 and itself) that prime numbers have, since 7 will be also be a factor.
