The Euclidean algorithm is a way to find the greatest common divisor of two positive integers. GCD of two numbers is the largest number that divides both of them. A simple way to find GCD is to factorize both numbers and multiply common prime factors. Let values of x and y calculated by the recursive call be x 1 and y 1. Note that? The extended Euclidean algorithm is particularly useful when a and b are coprime or gcd is 1.

Make sure that you have read the page about the Euclidean Algorithm or watch the video instead. That page explains how to construct a table using the Euclidean Algorithm. In the Extended Euclidean Algorithm we're going to do the same, but with some extra columns in the table. So if you have no idea what we're talking about, this page is going to be confusing, while it really doesn't have to be. Just read that page about the Euclidean Algorithm first. You can choose to read this page or watch the video at the bottom of this page. Both cover the same material, so there's no need to look at both.

What kind of Experience do you want to share? So we can conclude that A must evenly divide 0. Find anything on Euclid here. The Extended Euclidean Algorithm. Please Login to comment The Inverse can be read off as the last computed x value in the last line of the right column:. We first have to number the steps of the Euclidean algorithm since we will make use of the quotients q. Work Experiences. Objectives: 1 Understand the Extended Euclidean Algorithm to determine the inverse of a given integer. As usual, let's take a look at a simple example: Say, we want to find the inv erse of 15 mod GCD of two numbers is the largest number that divides both of them. What are some practical applications the Euclidean Algorithm might be used in?

Welcome to ExtendedEuclideanAlgorithm. A website with a calculator that shows you the intermediate steps and finally some clear explanations about the Extended Euclidean Algorithm. To understand the algorithms and the output of the calculator, we have some pages and videos explaining stuff: The Euclidean Algorithm The Extended Euclidean Algorithm Calculate the modular multiplicative inverse of a number modulo n using the Extended Euclidean Algorithm.

Suppose A and B are made up of chunks of size G If we subtract B from A the difference will also be some number of chunks of size G In fact, we can subtract several Bs from A and the difference will still be some number of chunks of size G If we subtract as many Bs as we can from A, then the remaining amount is the remainder when we divide A by B.

I apologise, but, in my opinion, you are not right. I can prove it.
