returnrn−1 Input two integers in the boxes below. Click "Find GCD" and then "Next Step" to follow the steps of the Euclidean Algorithm to find the greatest common divisor of the two integers. Click "Zoom" if the image gets too small to see. The animation starts with a rectangle wit...
Euclidean algorithm, procedure for finding the greatest common divisor (GCD) of two numbers, described by the Greek mathematician Euclid in his Elements (c. 300 bc). The method is computationally efficient and, with minor modifications, is still used by computers. The algorithm involves successively...
GCD的实现-辗转相除法: 在数学中,辗转相除法,又称欧几里得算法(Euclidean algorithm),是求取最大公约数的一种算法。辗转相除法首次出现于欧几里得的《几何原本》中的第Ⅶ卷,书中的命题ⅰ和命题ⅱ所描述的就是辗转相除法,而在中国,辗转相除法最早出现在《九章算法》中。 希腊数学家是这样处理的,在我们预先构造的矩...

It is also highly recommended to familiarize yourself with the concept of continued fractions. Euclidean algorithm and continued fractions Assume that we want to compute the greatest common divisor of A(x)A(x) and B(x)B(x) for degA≥degBdegA≥degB. For this purpose, we compute ...
The extended Euclidean algorithm is applied bygcdto compute unique polynomialss,tandginxsuch that s*A + t*B = g wheregis the monic greatest common divisor ofAandB. The results computed satisfy degree(s) < degree(B/g) and degree(t) < degree(A/g). The greatest common divisorgis returne...
