Mastering GCD of Two Numbers in Java Using Recursion – Step-by-Step Guide

Calculating the GCD of two numbers in Java using recursion is a common programming problem that enhances your understanding of recursion and mathematical algorithms. The greatest common divisor (GCD) is the largest number that divides two integers without leaving a remainder. In Java, you can solve this problem using a recursive function based on the Euclidean algorithm. To find the GCD of two numbers in Java using recursion, the function repeatedly calls itself by replacing the larger number with the remainder of the division until the remainder becomes zero. This approach minimizes code complexity and improves execution efficiency.
