Editing Factor (section)

== Mathematics ==
=== General mathematics ===
* [[Factor (arithmetic)]], either of two numbers involved in a multiplication
* [[Divisor]], an integer which evenly divides a number without leaving a remainder
* [[Factorization]], the decomposition of an object into a product of other objects
* [[Integer factorization]], the process of breaking down a composite number into smaller non-trivial divisors
* A [[coefficient]], a multiplicative factor in an expression, usually a number
* The act of forming a [[Quotient group|factor group]] or [[quotient ring]] in abstract algebra
* A [[von Neumann algebra]], with a trivial center
* [[Factor (graph theory)]], a spanning sub graph
* Any finite contiguous sub-sequence of a [[Combinatorics on words|word in combinatorics]] or of a [[Word (group theory)|word in group theory]].

=== Statistics ===
* An [[independent variable|independent]] [[categorical variable]].
** In [[experimental design]], the factor is a category of treatments controlled by the experimenter.
* In [[factor analysis]],  the factors are unobserved underlying ''hidden'' variables that explain variability in a set of correlated variables.
