Friendly numbers are pairs of numbers where one is the sum of the dividers on the other. For example, the dividers of 220 are 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, and 110, whose sum is 284. On the other hand, the dividers of 284 are 1, 2, 4, 71 and 142 and their sum is 220. Fermat also discovered pair 17,296 and 18.
Did you know that the difference between one number and the other that we get by writing it backwards is zero or a multiple of nine?
