Comment(by burcin):
I think the trouble here is our generic fraction field code, not how we
define the gcd of rational numbers.
For efficiency, we should represent QQ(x) as Frac(ZZ[x]), and do the
necessary normalisation of the denominator (it should be monic) when the
user accesses it with `.denominator()`.
