What is prime factorization?
Factoring a number means expressing it as a product of prime numbers. Every integer greater than 1 has a unique prime factorization (Fundamental Theorem of Arithmetic). Example: 360 = 2³ × 3² × 5.
Factorization is the basis for GCD, LCM, RSA cryptography and number theory algorithms.
