About this calculator

This calculator lists every divisor of a whole number, along with how many divisors it has and what they add up to — found by testing which numbers divide evenly into it, a direct application of the same factoring concepts used to compute a number's prime factorization.

Students use it to check math homework on factors and divisibility, and it comes up in number theory topics like identifying perfect numbers (where the divisors excluding the number itself sum to the number) or finding common factors between two numbers. Enter any whole number to see its complete divisor list instantly.
