Proper divisor

Further notions and facts

A positive divisor of ${\displaystyle n}$ that is different from ${\displaystyle n}$ is called a proper divisor or an aliquot part of ${\displaystyle n}$ (for example, the proper divisors of 6 are 1, 2, and 3). A number that does not evenly divide ${\displaystyle n}$ but leaves a remainder is sometimes called an aliquant part of ${\displaystyle n.}$
