1 is neither prime nor composite, so it isn't a valid target for factorization — only integers of 2 or greater are accepted.

It can factorize numbers under 1 trillion (1,000,000,000,000). Beyond that, the calculation could take a long time in the browser, so there's a limit.

It means the same prime factor is multiplied several times — 2³ is shorthand for 2×2×2.
