# Factors of

By using our online calculator to find the prime factors of any composite number and check if a number is prime or composite. This tool also draws the prime factor tree if the number is factorable and smaller than 16000.

## Prime Factors Calculator

 Enter a natural number to get its prime factors: Ex.: 4, 8, 9, 26, 128, etc. This calculator accepts numbers up to 10,000,000,000 (10 billion) Results: 0 (zero) isn't a prime number. Zero has an infinite number of divisors (any nonzero whole number divides zero). It cannot be written as a product of two factors. So, zero is also not composite. It falls in a class of numbers called ZERO-DIVISORS.
