Understanding Ratios
A ratio shows the relative size of two or more values. For example, if a screen has a width of 1920 pixels and a height of 1080 pixels, its aspect ratio is 1920:1080.
This calculator simplifies a ratio by finding the largest number that can divide both values evenly—their Greatest Common Divisor (GCD).
Simplification Method
To simplify a ratio A:B, you divide both numbers by their Greatest Common Divisor, GCD(A, B).
$$ \text{Simplified Ratio} = \frac{A}{\text{GCD}(A, B)} : \frac{B}{\text{GCD}(A, B)} $$
Enter two values to simplify their ratio.
