Abstract

The Pythagoreans were interested in perfect numbers, that is, numbers such as 6 and 28, which are equal to the sum of their proper divisors. They may also be described as numbers which are amicable with themselves. Nowadays we usually speak about the sum of all the divisors of a positive integer n, including n itself.
