what is the math to find out the output of more complex planetary gears? say something like 2:1-2:1-2:5 with the first 2 being the input and the 5 the "big gear"

if the big gear is 100% output its as simple to work out as a normal gear train (1:1.6) but if the big gear is locked than what would the math be? using brute force i work the output to be 1:26.666~ but what is the formula to get that?
