The Greatest Common Divisor (GCD) has plenty of real-world and programming applications, especially in areas like math, cryptography, and optimization. Let’s explore where and how GCD is used:

1. Simplifying Fractions GCD is super handy when you need to simplify fractions. By dividing the numerator and denominator by their GCD, you get the fraction in its simplest form. For example, consider the fraction 36/48. The GCD of 36 and 48 is 12, so the fraction simplifies to: 36/48=(36/12)/(48/12)=3/4.
