Among many other facilities the Presentations Application that I sell
through my web site has the convenience command FactorOut:

a + b + c // FactorOut[a] 

a (1 + b/a + c/a)

Let's say I have a polynomial:
          a+b+c
Is there any way I can force mathematica to produce the following result:
          a*(1+b/a+c/a)

I think such transformation of polynomials should be very common; however, I
have been trying all day and still can not get mathematica to do so
automatically.
