The greatest common factor of 3 and 5 is 1. This is because 1 is the largest positive integer that divides both 3 and 5 without leaving a remainder. Since 3 and 5 are both prime numbers, their only common factor is 1.

Oh, dude, the greatest common factor of 3 and 5 is 1. It's like the loneliest number, just hanging out by itself, not really mingling with any other factors. So yeah, 1 is the GCF of those two numbers. Cool, right?

The GCF of two prime numbers is always 1. 3 and 5 are both prime numbers so, GCF (3, 5) = 1.
