WebMar 7, 2011 · The least common multiple (LCM) of two integers is the smallest positive integer that is a multiple of both. The greatest common divisor (GCD) of two integers is the largest positive integer dividing both. The product of the two numbers is the product of the LCM and the GCD. Contributed by: Jacqueline D. Wandzura (March 2011) WebSep 8, 2024 · GCD (Greatest Common Divisor) of two given numbers A and B is the highest number that can divide both A and B completely, i.e., leaving remainder 0 in each case. GCD is also called HCF (Highest Common Factor). There are various approaches to find the GCD of two given numbers. Approaches:
