1. The two numbers are coprime.

The GCF is 1.

Two numbers are coprime if they have unity (1) as their only common factor. Example 1: 17 and 19 - any two prime numbers are also coprime. Example 2: 15 and 64 - neither is a prime, but they have no common factor except. The factorizations are 3x5 and 1x15; and 1 x 64 and 26, respectively.

Another term for co-prime is relatively prime.
