About the Prime Factorization Calculator
Prime factorization breaks a number down into the set of prime numbers that multiply together to produce it. Every whole number greater than 1 has a unique prime factorization.
Method: Repeatedly divide the number by the smallest possible prime until only prime factors remain.
Prime factorization is used to simplify fractions, find GCF and LCM, and underlies encryption algorithms in computer science.
