Example: Simplify aspect ratio

In order to simplify an aspect ratio, the greatest common divisor is determined. To do this, the larger number is divided by the smaller number with the remainder.

1920 ÷ 1080 = 1 R 840

Then divide the divisor by the remainder.
Repeat this step until the calculation works out.

1080 ÷ 840 = 1 R 240
840 ÷ 240 = 3 R 120
240 ÷ 120 = 2 R 0

The last divisor is then the greatest common divisor of the two starting numbers.

Divide the two numbers by the divisor you found

(1920 ÷ 120) : (1080 ÷ 120) = 16 : 9

Aspect Ratio = 16 ÷ 9 ≈ 1.778
