Math

Prime Factorization Calculator

Decompose any positive integer into its unique product of prime numbers — the fundamental "atomic" representation that underlies divisibility, fractions, modular arithmetic, and cryptography. The result is returned as a space-separated multiplication expression.

Math

Least Common Multiple Calculator

Find the least common multiple (LCM) of two positive integers — the smallest number that both divide evenly into. Indispensable for adding fractions with unlike denominators, synchronising periodic events, and scheduling tasks that repeat on different cycles.
