The LCM of these numbers is 120. LCM is Least Common Multiple.
The Least Common Multiple (LCM) of 10, 20, and 24 is 120.
LCM(30, 24, 20) = 120
The least common multiple of the numbers 20, 16 and 24 is 240.
12 is a factor of 24 so you need only consider the LCM of 20 and 24.20 = 4*5 24 = 4*6 So the LCM is 4*5*6 = 120.
The LCM of 20, 24, and 28 is 840
