1. If the greatest common factor of m and n is r, then the greatest common factor of Fm and Fn is Fr. How do I show that it is true for m=6 and n=9?

2. For any type of prime number p except 2 and 5, either Fp-1 or Fp+1 is divisible by p. How is this true for p=7 and p=11?

I just need to understand how to solve these types of problems. Thanks
