Definition:Divisor/Factorization
From ProofWiki
Definition
Let $x, y \in D$ where $\left({D, +, \times}\right)$ is an integral domain.
Let $x$ be a divisor of $y$.
Then by definition it is possible to find some $t \in D$ such that $y = t \times x$.
The act of breaking down such a $y$ into the product $t \circ x$ is called factorization.
Linguistic Note
The UK English spelling is factorisation.
