In this program, we are going to share a Java Program to Implement Stein GCD Algorithm. If you are a Java beginner and want to start learning the Java programming, then keep your close attention in this tutorial as I am going to share how to write a Java Program to Implement Stein GCD Algorithm.
Copy the below Java program and execute it with the help of Javac compiler. At the end of this program, We have shared the output of this program.

Stein GCD Algorithm Test
Enter two integer numbers
32984 10013
GCD of 32984 and 10013 = 589
