There are numbers called divisorial related to that problem.
Single responsability. It is like creating the sigma function with all the cases or to use gamma function instead of factorial.

... for calculating the sum/product of the divisors that don't rely on enumerating the divisors and then summing/multiplying them (As in Simonjsaunders demonstrates with the C++ sample) for this and the Sum Of Divisors Task. --[[User:Tigerofdarkness|Tigerofdarkness]] ([[User talk:Tigerofdarkness|talk]]) 20:58, 21 December 2020 (UTC)
