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
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,

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
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) =

Given the value of N, you'll have to find the value of G. The definition of G is given below:
Test instructions gives you a bunch of numbers and asks you to find them LMC (least common multiple). The first two are least common multiple equals they multiply and then one of their gcd (greatest common divisor), that three number of the largest
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
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
