The Least Common Multiple (LCM) for 15 20 120 is 120.
60, 120 and 18060 , 120 , 180
60, 120 and 180
The smallest number that 8 or 12 or 20 will all go in to is 120 120 = 20 x 6 = 12 x 10 = 8 x 15 as there is then no number that goes into 6 and 10 and 15 equally.
120
The LCM of 8, 10, and 15 is 120.Multiples of 8 are 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, 104, 112, 120, and so on.Multiples of 10 are 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, and so on.Multiples of 15 are 15, 30, 45, 60, 75, 90, 105, 120, and so on.So the LCM of 8, 10, and 15 is 120.The Least Common Multiple (LCM) for 8 10 15 is 120.
