It is numerology, with impressive pedigree: sum-of-divisors and “perfect numbers” are in Euclid: https://en.wikipedia.org/w/index.php?title=Perfect_number&ol... (for the numerology connection, search the page for "created in 6 days" and for "numerology"). See also https://en.wikipedia.org/w/index.php?title=William_of_Auberi... , and https://en.wikipedia.org/w/index.php?title=Aliquot_sum&oldid... which mentions:

> The mathematicians Pollack & Pomerance (2016) noted that one of Erdős' "favorite subjects of investigation" was the aliquot sum function.

This is the opposite of numerology. Numerology says that numbers have practical meaning, like 7 is lucky or 13 is unlucky. The point of pure math is that it has no practical meaning. We study it because we are free and not slaves.

It can be opposite but still as silly.
