The Least Common Multiple (LCM) of 4, 10, and 20 is 20.
The LCM of 8 and 10 is: 40Start by showing some multiples of both numbers:Multiples of 8: 8, 16, 24, 32, 40, 48, ...Multiples of 10: 10, 20, 30, 40, 50, ...The lowest common multiple is the lowest multiple that these two numbers have in common, making 40 the lowest common multiple in this case.Another way of doing this is to factor both of the numbers and multiply factors (skipping redundancies):8: 2, 410: 2, 52*4*5 = 40The LCM is 40.
