Summary of GCD and ex_gcd

Gcd () --- indicates the maximum common number. The common method is Euclidean algorithm. Ex_gcd () --- Extended Euclidean Algorithm Definition 1: A and B are two integers not all 0, that is, the maximum common divisor of A and B is the maximum

The oldest algorithm: Euclidean method (two natural number GCD)

In mathematics, the Euclidean algorithm, also known as Euclid, is considered to be the world's oldest algorithm (300 BC), which is used to find two GCD algorithms. The Euclidean method first appeared in Euclid's "Geometrical Original" (Volume VII,

Question link: HuangJingQuestion: Find the GCD with the K value of two numbers Ideas: First, find the maximum common divisor. My first thought was to create a large prime number table, and then continue division to find the largest K number, but

A good function (GCD) is used to calculate the least common number.

This function is a good one I accidentally saw. It is awesome and I like it. Is used to find the minimum public approx. A simple description is that gcd (a, B) indicates the maximum public factor of non-negative integers A and B, so: gcd (a, B) =

GCD and LCM Examples of two digits in C + +

1, to find the number of GCD two: #include int maxye(int a,int b) { int temp; while(a%b) {   temp=b;   b=a%b;   a=temp; } return b; } void main() { int aa,bb; cout cin>>aa; cout cin>>bb; cout } 2, to find the number of LCM two  #include int

The method of GCD and LCM of two numbers in C language _c language

GCD of two positive integers Train of thought: This is a very basic problem, the most common is two methods, Euclidean method and subtraction. The formula is f (x, y) = f (y, x%y), f (x, y) = f (y, XY) (x >=y > 0). It is not difficult to write an
