how to calculate greatest common divisor

First give the source code, explained below. #include void Main (){int a,b,c,d; //define four variablesscanf ("%d,%d", &a,&b);D=a*b; //Find out the product of two positive integerswhile (b!=0){C=a%b; //focus is here, a lot of people do not

Seeking greatest common divisor by the method of dividing set two numbers to A, B (b To find a proof from somewhere:principle and its detailed proofBefore introducing this method, we explain some of the characteristics of the integer division

1. Euclidean algorithm Euclidean algorithm, also known as the greatest common divisor, is used to calculate two integers a, b of the two-way. Its computational principle relies on the following theorem:Theorem: gcd (A, b) = gcd (b, a mod b) Prove:A

Seeking greatest common divisor and least common multipleAssuming that there are two numbers a and B, the greatest common divisor and least common multiple of a B are actually a problem, and it is concluded that the greatest common divisor of these

Title DescriptionDescriptionEnter two positive integer x0,y0 (2Condition: 1.p,q is a positive integer2. Require p,q to x0 for greatest common divisor, y0 as least common multiple.Trial: The number of all possible two positive integers that satisfy

Problem: Fast greatest common divisor of positive integers a, b?Euclidean algorithm (also known as the Euclidean method)Theorem: gcd (b) = gcd (a,a mod b)Proof: For any positive integer, a, B. If a>b, there are a=k*b+r namely r=a-k*b = r=a MoD

1040 Greatest Common Divisor Source: rihkddd Base time limit: 1 seconds space limit: 131072 KB score: 80 Difficulty: 5 level algorithm problem collection attention to give a N, ask 1-n this n number, with the greatest common divisor of N. For

The Stein algorithm, which is efficient for calculating gcd and LCM, is used to calculate large numbers:function gcd (b) {if (a = = b) {return A;} var bigger;var smaller;if (a>b) {bigger = A;smaller = b;} Else{bigger = B;smaller = A;} if (smaller = =

Algorithm OneAny >1 integer can be written in the form of one or more prime factor products, and the prime product factor appears in non-descending order.Then integer x, y can be labeled as:X=P1x1p2x2... pmxmY=p1y1p2y2... pmym(Where P1,p2,.... Is
