Thefactor

[Jason Yan]

Used to indicate that something specified will have a powerful, though unpredictable, influence on a result or outcome.

[Lanell]

Factor, in mathematics, a number or algebraic expression that divides another number or expression evenly—i.e., with no remainder. For example, 3 and 6 are factors of 12 because 12 ÷ 3 = 4 exactly and 12 ÷ 6 = 2 exactly.
