Hi all, quick question regarding relatively prime numbers.

Factors of 5: 1, 5

Factors of 20: 1, 2, 4, 5, 10, 20

Greatest common factor = 5

Since the greatest common factor of both numbers is 5, does that mean these numbers are not relatively prime towards each other? Or does 5 not count as a factor since it is one of the numbers I am checking?

Thanks!
