72, 144, 216, 288, 360, 432, 504, 576, 648, 720
All the common multiples of a set of numbers are the multiples of their lowest common multiple: lcm(5, 8, 10) = 40 → first three common multiples are 40, 80, 120
They are 40 and 80
40, 80, 120
8 = 2310 = 2*512 = 22*3LCM = 3*5*8 = 120So the two first common multiples of 8, 10, and 12 are 120 and 240.
40, 80, 120
120, 240, 360
They are: 40 80 and 120
40, 80 & 120
40, 80, 120
40, 80 ,120.
The first three common multiples of 8 and 12 are 24, 48, and 72.
The Least Common Multiple (LCM) for 8 10 15 is 120.
