Actually, the speeds were 16 2/3, 33 1/3, 45 and 78.26086957.  
Apparently, there was no exact standard for "78" and I always assumed 
until looking into it today that 78 was the exact RPM.

33 1/3 was chosen exactly, and 16 5/6 was half of that, used for longer 
symphonic pieces that could then fit uninterrupted on one side.  The 
sound quality suffered, but today's listeners to MP3 files probably 
wouldn't notice.  ;-)
