Quickly calculate the Greatest Common Factor (GCF) and Least Common Multiple (LCM) for two or more positive integers with our free online tool. Perfect for simplifying fractions, finding common denominators, and solving various math problems effortlessly.
Formula:
The Greatest Common Factor (GCF), also known as the Greatest Common Divisor (GCD), of two or more non-zero integers is the largest positive integer that divides each of the integers without a remainder.
The Least Common Multiple (LCM) of two or more non-zero integers is the smallest positive integer that is a multiple of each of the integers.
There is a useful relationship between GCF and LCM for two numbers (a, b): GCF(a, b) × LCM(a, b) = |a × b|
