Euclidean algorithm - Wikipedia, the free encyclopedia
In mathematics, the Euclidean algorithm (also called Euclid's algorithm ) is an efficient method for computing the greatest common divisor (GCD), also known as the greatest common factor (...

Indeed, every common divisor of a and b also divides r. ... Note: Euclid's algorithm is not the only way to determine the greatest common factor of two integers. If you can find the prime factorizations of the two numbers you can easily determine their gcd as the intersection of the multisets formed by their prime factors.

The above procedure, called Euclid's gcd algorithm, extracts the greatest common divisor x, because any other common divisor y divides evenly into each difference and remainder along the way, until finally, y divides x. The result, x, is truly a "greatest common divisor", since it contains every other common divisor y.

In this paper we give a modular algorithm to compute one sided greatest common divisors for matrix polynomials, improving on the fraction free algorithm by Beckermann and Labahn. We define lucky homomorphisms for the modular algorithm and give bounds on the coefficients in the results computed. ... - Cheng (2003) (Correct);

If we do the process illustrated on the previous page for any equation , we eventually get one of the coefficients as zero and the other as . [In fact, this process is usually presented as ``Euclid's algorithm for finding the greatest common divisor.'']
