WebBeing an (n k) with smaller k = 6 < 17, this follows by induction. Since the same proof works for any prime p, we conclude that no prime divides the reduced denominator of (39 17), therefore it is an integer. QED Informally, the reason that this works is because the denominator sequence starts at 1, which is coprime to every prime p.
