Time Limit Exceeded

Samuel Onate (14)
I'm trying to get this code to run without the
time limit error. (Solo learn android app compiler) It's obviously not too complex. 1 function, the main function, 1 calculation, I looked up 'time limit errors' & found something about fprint instead of cout. But, i actually like using cout unless someone can drill in my head (nicely) that fprint is better.

The LcmGcd function runs into an infinite loop for some inputs.

Lines 14 and 16 are the same. I'm sure that isn't what you intended.
