Break all the coefficients into their prime factorizations:

12%2Ar%5E4%2As%5E3%22%22=%22%222%5E2%2A3%5E1%2Ar%5E4%2As%5E3
18%2Ar%5E6%2As%5E5%22%22=%22%222%5E1%2A3%5E2%2Ar%5E6%2As%5E5
36%2Ar%5E9%2As%5E4%22%22=%22%222%5E2%2A3%5E2%2Ar%5E9%2As%5E4

Pick the largest power of 2, 3, r and s.

LCD%22%22=%22%222%5E2%2A3%5E2%2Ar%5E9%2As%5E5
