Divisor (mathematics) in the context of "Rate (mathematics)"

In mathematics, a divisor of an integer ${\displaystyle n,}$ also called a factor of ${\displaystyle n,}$ is an integer ${\displaystyle m}$ that may be multiplied by some integer to produce ${\displaystyle n.}$ In this case, one also says that ${\displaystyle n}$ is a multiple of ${\displaystyle m.}$ An integer ${\displaystyle n}$ is divisible or evenly divisible by another integer ${\displaystyle m}$ if ${\displaystyle m}$ is a divisor of ${\displaystyle n}$; this implies dividing ${\displaystyle n}$ by ${\displaystyle m}$ leaves no remainder.
