Irrational numbers can be divided into algebraic numbers and transcendental numbers. Algebraic numbers are those which are the solutions to algebraic equations with integer coefficients: for example, x^2 = 2. Transcendental numbers are those for which there are no corresponding algebraic equations. pi, e are two examples.
As a noun, a factor is a number or algebraic expression by which another is exactly divisible. As a verb, factoring is a process of breaking down a number or algebraic expression into smaller component parts.
