I think this task is like factorial. We shouldn't miss it.
== Depends on the algorithm you use... ==
I think what Blek is trying to say is that finding the sum of the proper divisors of a number isn't necessarily the same as finding the divisors and adding them up. There are other algorithms other than the "obvious" one. --[[User:Tigerofdarkness|Tigerofdarkness]] ([[User talk:Tigerofdarkness|talk]]) 19:29, 21 December 2020 (UTC)
: +1 for this. Perhaps the task should ask for more than the first 100 which is trivial, provides no insight, and can be done with any algorithm. Perhaps asking for the largest sum of divisors in the first 3 million positive integers would discourage trivial factorization algorithms.--[[User:Nigel Galloway|Nigel Galloway]] ([[User talk:Nigel Galloway|talk]]) 15:07, 9 March 2021 (UTC)
