One of the first programming tasks is to find the Greatest Common Divisor (GCD). Developing effective algorithms requires knowing how to use recursion in Java to perform GCD. By dividing the problem into smaller, more comprehensible components, recursion streamlines the reasoning. You must comprehend the Euclidean approach, which reduces the issue size gradually, in order to use recursion to calculate the GCD in Java. The recursive call uses the modulus operator to decrease the problem in the base case, which is when one number becomes zero.
