LCM(a,b) = (a × b) / GCF(a,b). Using prime factorization: take the highest power of each prime factor present in any number. Example: LCM(12,18) = LCM(2²×3, 2×3²) = 2²×3² = 36. Used to add/subtract fractions (find LCD), schedule repeating events, and solve synchronization problems. LCM grows quickly; for many numbers, use the step-by-step approach.
