There are several ways of calculating LCMs. I like the "Product/HCF" method, which is easiest with two numbers but can be used for these four numbers:
By inspection, LCM of 45 & 10 = 90, LCM of 12 & 8 = 24 so now find the LCM of 90 & 24:
90 = 2 x 3 x 3 x 5; 24 = 2 x 2 x 2 x 3. The common factor is 2 x 3 ie 6 so the LCM is the product of 90 & 24 divided by 6 which is 360.
LCM(45, 10, 12, 8) = 360.
The LCM of 8, 10, 12 and 45 is 360.
The LCM of 8, 10, 12 and 45 is 360.
The least common multiple of 8, 30 and 45 is 360.
The LCM is 120.
LCM(8, 10, 12) = 120.
LCM(8, 12, 10) = 120.
The LCM is: 360
LCM of 5 10 12 8 is 120.
Least Common Multiple (LCM) for 8 12 10 is 120.
For the values: 25, 12, 10, 8 the LCM is: 600
The LCM of 4 and 8 is 8. The LCM of 6 and 10 is 30. The LCM of 7 and 8 is 56. The LCM of 9 and 12 is 36.
