Great LCM exercise. Done!

2 things are really interesting:

1. How to find the right test cases. I think I'll probably need to go
back and re-read how to do an exhautisive testing

2. Python 3's floor division versus true division (// and /) operators
are interesting. This exercise discussion helped me:
