Road to IMO!

Congratulations to one of the most brilliant young minds in the Brilliant community for passing the PMO Area Stage Qualifiers - @Sean Anderson Ty. I say that this is a great feat for there are many who had the chance but wasn't able to qualify (Yep, I'm talking about me) He also lives/studies in the same city as I am, so I am proud that maybe one of ours is going to be part of IMO. As a gift, I give these Fibonacci problems (Who doesn't like proving?) 1) Let mm and nn be positive integers. Prove that, if mm is divisible by nn, then, fmf_{m} is divisible by fnf_{n}. 2) Let mm and nn be positive integers whose greatest common divisor is dd. Prove that the greatest common divisor of the Fibonacci numbers fmf_{m} and fnf_{n} is the Fibonacci number fdf_{d}
