The number are small enough to easily work out all factors. For each number, Start with 1, then divide by 2, then by 3, etc. if it doesn't divide evenly, it's not a factor, and you can skip to the next number... They will eventually start duplicating, ie 2x36 = 36x2, so you don't have to work it twice. It's longer, but easier. HTH
