Understanding The Math: GCD

When you input a resolution like `1920x1080`, how do we know it's `16:9`? We use the Greatest Common Divisor (GCD). The largest number that perfectly divides both 1920 and 1080 without a remainder is `120`. If you divide `1920 / 120 = 16`, and `1080 / 120 = 9`. Therefore, the ratio is exactly 16:9.
