I am really struggling with this Fibonacci number problem. If the greates common factor of "m" and "n" is "r", then the greatest common factor of Fm and Fn is Fr. Show that this is true for m=6 and n=9. I am so confused

Answer 1

F6 = 8
F9 = 34

gcd of 6 and 9 is 3

F3 = 2, the gcd of 8 and 34

Answer 2
