In mathematics, a divisor of an integer n, also called a factor of n, is an integer which divides n without leaving a remainder. The statement "m is a divisor of n" can be written as .[1][2] Any number is always divisible by 1 and itself, which are two of the divisors. A prime number is a number with no other divisors. The positive divisors of a number n, other than n itself, are the proper divisors of n.[3]
Finding one or more factors of a given number is called factorization.
