I had a lot of fun working on this problem:

Given n, find x, y and z such that x y z = n and x + y + z is minimal; for instance, given n = 1890, the correct answer is (9 14 15).

Your task is to write a program to find x, y and z. When you are finished, you are welcome to read or run a suggested solution, or to post your own solution or discuss the exercise in the comments below.
