18180 = (2132)180 = 21803360

Let N be the least integer power of 12 that is divisible by 18180.

12N = (2231)N = 22N3N

So we divide:

 = 2(2N-180)3(N-360).

The smallest integers N can be must be just enough to make
sure those powers of 2 and 3 are not negative.

So N-360 = 0 or N = 360, 

(and certainly then 2N-180 = 360-180=180 is not negative.)

So N = 360.
