The LCM is 120.
LCD(8, 20, 15) = 120
The composite factors of 120 are 4, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120

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.
60, 120 and 180
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.
The LCM is 120.

4, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
LCD(8, 20, 15) = 120
The composite factors of 120 are 4, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
The factors of 20 are 1, 2, 4, 5, 10, and 20. The factors of 120 are 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, and 120. The common factors of 20 and 120 are 1, 2, 4, 5, 10, and 20. Therefore, the least (smallest) common factor is 1.
