A proper divisor of a positive integer is a positive integer that divides the number without leaving a remainder.
In mathematics, a proper divisor of a whole number is any positive integer other than the number itself.
The proper divisors of a natural number are all the positive integers that divide the number without leaving a remainder.
To find the proper divisors of an integer value, you need to identify all the positive integers that divide the number evenly.
A proper divisor of a number can be expressed as a product of its prime factors.
