Finding Re-Used Parts In an Assembly??

Hello. I'm new in the Engineering Field and could use some help. My assignment was to rename an assembly and all the parts contained in the assembly, and once done with that, start doing drawings for the previously mentioned parts and assemblies. Is there any way that I can find out what parts are re-used? Where? And how many times? Thanks for any help!

P.S- I would not have a problem doing this on a small assembly, but the project I'm working on has 275+ parts and 20+ sub assemblies.
