(20:32:14) JoshuaZelinsky: refactor is a word
(20:32:43) Sniffnoy: what, to factor again?
(20:33:21) JoshuaZelinsky: kinduv
(20:33:30) JoshuaZelinsky: its a technical word
(20:34:07) JoshuaZelinsky: to refactor n, means(at least one definition) to replace n with the smallest refactorable number divisible by n
(20:34:27) Sniffnoy: ...what's a refactorable number?
(20:35:09) JoshuaZelinsky: a number is said to be refactorable(or tau) of d(n) | n where d(n) is the number of divisors of n
(20:35:19) Sniffnoy: oh
(20:35:47) Sniffnoy: I know why they're called tau numbers, why are they called refactorable?
(20:36:12) JoshuaZelinsky: its some sort of vague analogy
(20:36:25) JoshuaZelinsky: you factor it to get the number of divisors, and get a factor
(20:36:45) Sniffnoy: heh

[Note: they're called tau numbers because the function d(n) used above is often called τ(n)]
