Join our newsletter for the latest updates. The Euclidean algorithm is based on the principle that the greatest common divisor of two numbers does not change if the larger number is replaced by its difference with the smaller number. The Least Common Multiple (LCM) of two integers a and b, usually denoted by LCM (a, b), is the smallest positive integer that is divisible by both a and b. Eg: Feint distance between “abcde” and “Thin pbcq” is 1+0+0+1+1=3 We will calculate GCD of two natural numbers using recursive & iterative algorithm. 6 â¦ Program to find LCM using recursion. For example. Finally, return the product of elements in union. 2 Step: then Store Maximum of A and B in variable max. For example, Java GCD of 8 and 12 is 4 because both 8 and 12 are divisible by 1, 2, and 4. GCD also known as HCF (Highest Common Factor). We can also use GCD to find the LCM of two numbers using the following formula: LCM = (n1 * n2) / GCD. GCD is calculated using Euclidean algorithm and LCM is calculated using reduction by GCD Eucid algo for calculating GCD is: Lets say , there are two numbers , a and b so GCD of two numbers = GCD (b,a%b) and GCD(a,0)=a LCM can be calculated using reduction by GCD : LCM of two numbers a and b = a * b/GCD(a,b) Java program : When you run above program, you will get following output: â¦ TrainingMug 11,210 views.
