The flowchart given here represents the calculation of gcd greatest common divisor.

Algorithm and flowchart for greatest common divisor. The euclidean algorithm takes as an input two positive integers a and b and assumes that denotes a modulo operation. This theorem can be easily proven. Learn to draw the flowchart for the same gcd program in c https y. In mathematics the euclidean algorithm or euclid s algorithm is a method for computing the greatest common divisor gcd of two usually positive integers also known as the greatest common factor gcf or highest common factor hcf.

Hence we use the euclidean algorithm euclid s algorithm to calculate the greatest common divisor of two natural numbers. The greatest common divisor gcd of two numbers is the largest number that divides both of them. The euclidean algorithm is one of the oldest algorithms in common use. The above flowchart is drawn in the raptor tool.

Greatest common divisor explaination and flow chart. Wikipedia the flowchart example euclidean algorithm was created using the conceptdraw pro diagramming and vector drawing software extended with the mathematics solution from the science and education area of conceptdraw solution park. Gcd of two numbers 12 24 is 12. It appears in euclid s elements c.

Let a b be the two numbers step 2. You will better understand this algorithm by seeing it in action. Assuming you want to calculate the gcd of 1220 and 516 let s apply the euclidean algorithm. The code for calculating the lcm and gcd is given in the below link.

In mathematics gcd or greatest common divisor of two or more integers is the largest positive integer that divides both the number without leaving any remainder. The euclidean algorithm does not require any factorization at all. Br the gcd of two positive integers is the largest integer that divides both of them without leaving a remainder the gcd of two integers in general is. What is gcd or greatest common divisor.

Pseudo code of the algorithm. Euclidean algorithm for greatest common divisor gcd the euclidean algorithm finds the gcd of 2 numbers. The euclid s algorithm or euclidean algorithm is a method for efficiently finding the greatest common divisor gcd of two numbers. In mathematics the euclidean algorithm or euclid s algorithm is an efficient method for computing the greatest common divisor gcd of two integers numbers the largest number that divides them both without a remainder.

Let s say we have two numbers that are 63 and 21. In this tutorial we will learn to find gcd or greatest common divisor using recursion. Learn about the greatest common divisor and how to find it through euclid s algorithm.
