WebIn this tutorial we will learn to find GCD or Greatest Common Divisor using recursion. What is GCD or Greatest Common Divisor. In mathematics GCD or Greatest Common Divisor of two or more integers is the largest positive integer that divides both the number without leaving any remainder. Example: GCD of 20 and 8 is 4. The pseudo code of GCD ... WebDue to the binary representation, operations are performed in linear time based on the length of the binary representation, even for very big integers. On the other hand, modulo applied in algorithm 10.2 has worse time complexity. It exceeds O(log n · log log n), where n = a + b. Thus the time complexity is O(log(a · b)) = O(log a + b) = O ...
