comment Finding largest Range in a list
@Kuba No, I would like the answer to be zero, since Range[2] is not a subset of the given set.

comment Finding largest Range in a list
Nice. Is the Length /@ necessary? Doesn't Max[{{1,2,3}}] yield 3?

comment Lists of integers coprime to another list
Yes, I guess that's much easier than the complicated scheme I was cooking up. Thanks.

comment Is there a way to rewrite integrals in Mathematica using u substitution?
Well, I don't see why you can't adapt what I did to that case, using w-x->u.

comment Is there a way to rewrite integrals in Mathematica using u substitution?
How much simpler could it be? If you want to compute $\int x^2\,dx$ using the substitution $u = \cos x$ (I realize you wouldn't do this), write in Mathematica Integrate[ReleaseHold[x^2 HoldForm[D[x,u]]/.x->ArcCos[u]],u] and then resubstitute for $u$.

If I surround all of this with Integrate[...,u], it works for me. You should really be asking this on Mathematica.se
