WebJan 20, 2024 · Solution: The LCM of two numbers can be found more easily by first finding their greatest common divisor (GCD). Once the GCD is known, the LCM is calculated by the following equation L C M = a × b GCD (a,b) The GCD of 4 and 6 is 2. Using the above equation, we find LCM (4, 6) = 4 × 6 GCD (4,6) LCM (4, 6) = 24 2 WebC Program to find LCM of Two Numbers using GCD In this LCM program, we are going to calculate the Least Common Multiple of those two values using the While Loop. TIP: The basic formula behind the Least Common Multiple in C is: LCM (a, b) = (a * b) / GCD. We already explained the GCD in our previous article.
