    You can solve this consecutively. First, let us find LCM(12, 16).

    It is 48. (This is because their GCD is 4, and LCM(12, 16) = 12*16/4 = 12*4 = 48).

    And now let us find LCM(48, 20). It is 240. Again, first I found GCD(48, 20), which is 4 again. Then, LCM(48, 20) = 48*20/4 = 48*5 = 240.

    So, the answer is 240.
