1, and only 1. There are no common factors (whole numbers) between those three numbers but one.
lcm(8, 5, 12) = 120 8 = 2^3 5 = 5 12 = 2^2 x 3 lcm = 2^3 x 3 x 5 = 120
The Least Common Multiple (LCM) for 12 5 20 3 is 60.
lcm(3, 5, 8, 4, 6, 12) = 120
It is: 60
660
Prime factors are: 3, 5, 2, 22 and 3 So LCM = 3*22*5 = 60
factor 12=2*2*3 20=2*2*5 25=5*5 LCM=2*2*3*5*5=300
LCM of 12 and 3 is 12.
The answer is 60. The way I approached this is: LCM of 3 and 6 is 6 (since 3 x 2 = 6 and 6 x 1 = 6), so you can disregard the 3. LCM of 4 and 6 is 12 ( 6 = 3 x 2 & 4 = 2 x 2) they have a common factor of 2, so 12 = 3 x 2 x 2. So now you have to figure LCM of 5 and 12. 5 and 12 only have a common factor of 1, so LCM of 5 & 12 is 5 times 12 = 60.
The LCM of 3 and 12 is: 12 3:3,6,9,12 12:12,24,36
The LCM is 60.
LCM(9, 12, 5, 3) = 180.
