 @ Chammo, Good explanation!! We really appreciate your contribution to this forum. Keep posting!
It is because two numbers are said to be co prime if 1 is the only common factor (exact divisor).

Two numbers are said to be co prime numbers if they do not share any common divisor except for 1. For example, 9 and 10 are co-primes. Number 9 has factors 1,3,9 and 10 has 1,2,5,10. Only 1 is common. So, these two are co-prime numbers.

hope it helps !!
