Calculate the maximum common divisor gcd (A, B) of two numbers & proves Euclidean Algorithm

Calculate the maximum common divisor of two numbers A and B. We can think of enumerating each positive integer from [1, min (A, B: #includeusing namespace std;int gcd(int a,int b){ int ans=1; for(int i=2;i>a>>b; cout   However, when a and B

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,

The realization code _c language of GCD and LCM by recursive method

Mathematical principle:There are two numbers of NUM1 and num2, assuming that the NUM1 is relatively large. Make remainder r = num1% num2.When r = = 0 o'clock, that is, NUM1 can be divisible by num2, obviously num2 is the gcd of these two

Parsing: Seeking gcd "principle of Euclidean division method"

Title: Enter two positive integers m and n, and ask for their gcd and LCM. In c language code as follows: #include void Main () { int p, r, N, M, temp; printf ("Please enter two positive integers:"); scanf ("%d,%d", &n, &m); if (n This

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) =
