Algorithms Extended Euclidean Algorithm We will demonstrate Extended Euclidean Algorithm. We will see how you can calculate the greatest common divisor in a naive way which takes O(N) time complexity which we can improve to O(log N) time complexity using Euclid's algorithm. Extended Euclidean Algorithm takes O(log N) time complexity

Algorithms Minimum operations to make GCD of array a multiple of k We are given an array and k, we need to find the minimum operations needed to make GCD of the array equal or multiple of k. Here an operation means either increment or decrement an array element by 1.

greatest common divisor Euclidean Algorithm to Calculate Greatest Common Divisor (GCD) of 2 numbers The Euclid's algorithm (or Euclidean Algorithm) is a method for efficiently finding the greatest common divisor (GCD) of two numbers. The GCD of two integers X and Y is the largest integer that divides both of X and Y (without leaving a remainder).
