Any two composite numbers who do not share the same prime factors.15 = 5x322 = 11x2So 15 and 22 have a GCF of 1
No. Two composite numbers, like 4 and 9, can have a GCF of 1. They are said to be relatively prime or co-prime.
Positive integers with only two factors.
Relatively prime numbers share no common factors other than 1.
Not all composite numbers are even, but all even numbers except 2 are composite.
