The number that shows up only to split and vanish, leaving a product behind.

means A number or quantity that divides evenly into another, or more broadly, one of the elements that multiplies together with others to produce a result.

from From Latin 'factor' meaning 'doer' or 'maker,' built from 'facere,' to do or make — the same root behind 'fact' and 'manufacture.' It entered English first as a word for an agent who acts on someone else's behalf, like a trading agent or steward. The mathematical sense — a number that 'makes' a product when multiplied by another — grew out of that same idea of an active contributor: a factor is one of the makers of the final result.
