Eliminating common factors?

I have a simple, totally algebraic symbolic calculation that displays 
its output in the form (rewritten here using TeX notation)

      4 ( {a \over 4 } + { b \over 4 c } )

where a, b and c are fairly simple products of purely algebraic 
quantities; \over is the TeX notation for a display fraction; and the 
curly brackets are just for TeX purposes and are not there in the actual 

Is there any Assumption for Simplify, or any other _simple_ way, to get 
rid of those (utterly!!!) superfluous 4's?

[I suppose the real question is, why doesn't M cancel 'em the hell out 
in the first place?!?!]
