What's the algorithm to calculate aspect ratio?
...numbers. So the GCD for 6 and 10 is 2, the GCD for 44 and 99 is 11.
For example, a 1024x768 monitor has a GCD of 256. When you divide both values by that you get 4x3 or 4:3.
A (recursive) GCD algorithm:
function gcd (a,b):
if b == 0:
return a
return gcd (b, a mod b)
