The GCF is 1.
The GCF of two prime numbers is always 1. 3 and 5 are both prime numbers so, GCF (3, 5) = 1.
The only factor that all of these numbers share is 1 since 3 and 5 are prime. So 1 is the gcf of this set of numbers.
The GCF is 3.

You need at least two numbers to find a GCF. If that's 3 and 15, the GCF is 3.
No. The GCF of 3 and 5 is 1. The GCF of 3 and 9 is 3.
The GCF of 5 and 10 is 5.
The GCF is 5.
factor out both numbers to get 102=2*3*17 50=2*5*5 the GCF is 2
The GCF is 5.
