WebSep 15, 2024 · We can also find the gcd of two numbers using the iterative method for Euclid’s algorithm. The concept is used in the calculation of gcd using iteration: 1) Take two numbers a and b as inputs. 2) If a==0, then gcd is b. 3) Else if b==0,then gcd is a. 4) Else, while (b!=0) {. r=a mod b; WebIf this test condition is not true, max is incremented by 1 and the iteration continues until the test expression of the if statement is true. The LCM of two numbers can also be found using the formula: LCM = (num1*num2)/GCD. Learn how to find the GCD of two numbers in C programming.
