The first method to find the greatest common divisor of three numbers in Java is using the Euclidean algorithm:

Java Program for GCD of Three Numbers (Euclidean Algorithm)

In mathematics and computer science, the concept of the Greatest Common Divisor (GCD) holds immense importance. The GCD of three numbers is the largest positive integer that divides each of them without leaving a remainder. It's a fundamental mathematical concept that finds application in various domains, including number theory, cryptography, and algorithm design.
In this tutorial, we will learn how to calculate the GCD of three numbers in Java programming. While there are established algorithms for finding the GCD of two numbers, extending this to three may seem like a daunting task at first glance. However, with the power of Java and some clever algorithm design, we can easily tackle this challenge.
