in thread Puzzle: What is the largest integer whose digits are all different (and do not include 0) that is divisible by each of its individual digits?

You can make it even faster by just dropping 5 from the list, since including a 5 excludes all even digits and restricts the solution length to 5 digits (which we quickly prove is too short). You can also make it faster by more efficiently skipping the redundant permutations. That's the nature of quick hacks. (:
