Two [or more] numbers are said to be relatively prime or coprime if they have no factor in common [other than 1]. They need not be prime numbers.
Equivalently, a set of numbers is relatively prime if and only if their GCF is 1.
Thus, 2*7 = 14 and 3*5 = 15
Neither 14 nor 15 is a prime but they are relatively prime since they do not have a factor in common.
