A perfect number, such as 6, is a number that equal the sum of its proper divisors. So for 6 those are 1,2 and 3. The sum of 1+2+3=6. The first four perfect numbers are: 6, 28, 496, 8128 It is worth noting that perfect numbers are pretty rare. Look how far apart the 3 and 4th one are. This pattern continues and the distance between the 4 and 5 large as well! Here are the first 4 again and a few more so you can appreciate how far apart they are after the first 3. 6, 28, 496, 8128, 33550336, 8589869056, 137438691328, 2305843008139952128, 2658455991569831744654692615953842176, 191561942608236107294793378084303638130997321548169216
