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)
:Yep, it is allied, but deficient, perfect, abundant number classifications as well as Amicable pairs are based on them. --[[User:Paddy3118|Paddy3118]] ([[User talk:Paddy3118|talk]]) 18:34, 16 December 2014 (UTC)
::It seems like it'd be easier to just use the "proper divisors" definition in other tasks where appropriate rather than having a separate task with essentially the same code (except for maybe esoteric languages). Especially since any definition with "factors of an integer" could be made using "proper divisors" with one or two extra additions or subtractions. It just doesn't seem worth it. It looks to me like having a task to "print the number 3" and another task to "print the number before 4". --[[User:Mwn3d|Mwn3d]] ([[User talk:Mwn3d|talk]]) 19:11, 16 December 2014 (UTC)
