🔢Prime Factorisation Calculator

Prime factorisation expresses a composite number as a unique product of primes (Fundamental Theorem of Arithmetic). Used in LCM, GCF calculations, cryptography, and simplifying fractions.

Fun Fact

RSA cryptography's security rests on factoring large numbers being computationally infeasible — a 2048-bit number would take classical computers longer than the universe's age to factor.
