Just Perfect, Part 2
Scott, Paul
Australian Mathematics Teacher, v63 n2 p3-5 2007
In "Just Perfect: Part 1," the author defined a perfect number N to be one for which the sum of the divisors d (1 less than or equal to d less than N) is N. He gave the first few perfect numbers, starting with those known by the early Greeks. In this article, the author provides an extended list of perfect numbers, with some comments about their discovery. He also briefly discusses Euclid's proof and Mersenne primes. [For Part 1, see EJ769967.]
