It is interesting because if you allow negative numbers it is trivial to solve, with integers in the range -15 .. 15 (not going to give you that solution, just try it, it isn't hard to solve). But when you add the restriction that the numbers must be positive whole integers it becomes a incredibly difficult problem that you need a computer to brute force even if you know the mathematical trick behind it. The smallest integer solution for the 3 variables, IIRC is a massive number for each, like each is 80-digits long.
