The explanation on the J implementation here makes a good point: is this task just a trivial change of [[Factors of an integer]]? --[[User:Mwn3d|Mwn3d]] ([[User talk:Mwn3d|talk]]) 17:09, 16 December 2014 (UTC)
== Definition ==
I don't believe the definition used is correct. In particular "always includes 1" doesn't follow from the definition given at the linked site, or [http://mathworld.wolfram.com/ProperDivisor.html MathWorld] or [http://oeis.org/A032741 OEIS].
A simple definition from Mathworld: "A positive proper divisor is a positive divisor of a number n, excluding n itself."
