We are trying to find a common multiple of 12, 15, 18 and 27 which is of four digit size. This number should have to be a multiple of the least common multiple (L.C.M) of these four numbers.
L.C.M. of these four numbers is 540.
Largest four digit multiple of this number can be easily found by Brute force method.
Lets take 540 * 20 = 10800 (five digit number)
So we have to take a lesser multiple and thus by following this brute force method, we can get the result.
The largest four digit number divisible by 12, 15, 18, 27 is 9720 (540 * 18).
