Comment(by SimonKing):
I just updated my patch, and I hope it addresses all your remarks. The
typos are fixed, the old gcd of the rational field is now removed, and: I
also added gcd/lcm for general fields. I am sorry that this makes #9819 a
duplicate.
And I hope that I did not confuse gcd and lcm in the following setting:
{{{
sage: GF(2)(1).gcd(GF(2)(1))
1
sage: GF(2)(1).gcd(GF(2)(0))
1
sage: GF(2)(0).gcd(GF(2)(0))
0
sage: GF(2)(1).lcm(GF(2)(0))
0
sage: GF(2)(1).lcm(GF(2)(1))
1
}}}
That's implemented as element methods for the category of `Fields()`.
Somehow, the category framework is cool, isn't it?
