The least common multiple (LCM) of 18, 21, and 56 is 504.
The LCM would be 4536 - because 56 divides exactly into it 81 times !
The LCM is: 147
Th LCM of 21 and 42 is: 42
The LCM is: 1,176
LCM(21, 49, 56) = 1176
21 = 3*7 56 = 23*7 LCM = 23 * 3 * 7 = 168
56.
lcm(21, 56) = 168. 21 = 3 x 7 56 = 2^3 x 7 lcm = 2^3 x 3 x 7 = 168
The Least Common Multiple (LCM) for 28 21 56 is 168.
The answer you're looking for is... 56
