Dupe?

The explanation on the J implementation here makes a good point: is this task just a trivial change of Factors of an integer? --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 MathWorld or OEIS.

A simple definition from Mathworld: "A positive proper divisor is a positive divisor of a number n, excluding n itself."
