Removing constant multiples from polynomials

I am working on an algorithm which manipulates sets of polynomials.
Often it produces (after an application of FullSimplify) polynomials
like:

1276(x-1)(y-2)/397

I'm only interested in the solutions to the polynomial, so to me this
is "equivalent" to:

(x-1)(y-2)

As a short-term solution I call "GroebnerBasis" on the single
polynomial, which seems to perform this simplification. However is
there a simpler method?

Thank you,

Chris
