Co-prime numbers have a GCF of 1, that is, they don't share any common prime factors.
If your number is 15, with a prime factorization of 3 x 5, pick a number that doesn't include 3 or 5.
2 x 11 is 22
15 and 22 are co-prime.
No 5 is a prime number and 12 is composite number
No because 31 is a prime number but 62 is a composite number
No because 5 is a prime number whereas 6 is a composite number
Any two coprime numbers
To find a composite number, check if the number can be divided by 2,3,4,5, ect. If it can, it`s composite. If not, it`s prime.
Factor it. Once you find a third factor, it's composite.

There is no such thing as a coprime number.Two integers are said to be relatively prime (or coprime) if they have no common positive factor, other than 1. Examples:Any two different prime numbers are coprime.16 and 27 are coprime.14 and 18 are not coprime. They have the common factor 2.
coprime numbers with 18 are : 17 and 19.
No because they are both composite numbers having more than two factors

Since 25 and 27 are coprime, any third number - even if it shares a factor with one of these numbers - is bound to form a triplet whose HCF is 1.
