The Mathematics Behind It
How it Works (Euclid's Engine)
Instead of relying on slow prime factorization methods, this tool leverages Euclid's Algorithm to find the Great Common Divisor instantly. The Least Common Multiple is then efficiently derived using the relationship: LCM(a,b) = (|a| * |b|) / GCD(a,b).
