Help needed in LCM range query problem

Given an array A of N (N<=2*10^4) elements and Q(Q<=10^6) queries. Each array element A[i]<=60.

In each query you are given a number K (K<=N). Compute LCM for all subarrays of size K and report the smallest value of LCM found. Please suggest some approach for this problem.

I tried storing precomputed results for subarrays of size<=sqrt(N) and for subarrays with size>sqrt(N), I used the brute force way but got TLE.
