What is prime factorization?
Prime factorization expresses any integer as a unique product of prime numbers — called the fundamental theorem of arithmetic. For example, 360 = 2³ × 3² × 5. This calculator uses trial division up to the square root of the input, which is exact and fast for values up to a trillion. From the prime factors it also derives the full divisor list and factor pairs.
