Queries with GCD

You are given a sequence A with N elements and Q queries on this sequence. In each query, you are given two indices L and R; you should compute the maximum value of the greatest common divisor (GCD) of two elements Ax, Ay satisfying L ≤ x y ≤ R. Input - The first line of the input contains two space-separated integers N and Q. - The second line contains N space-separated integers A1, A2, ..., A
