120
Make a list of the multiples of each number until you find a number which is on all three lists. Or, it is usually easier to find the LCM of 2 of the numbers, then find the LCM of that answer and the 3rd number.
10, 20, 30, 40, 50, 60, ...
12, 24, 36, 48, 60, ...
The LCM of 10 and 12 is 60. Now find the LCM of 60 and 8:
60, 120, ...
8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, 104, 112, 120, ... (whew!)
The LCM of 10, 12 and 8 is 120.
There is also a method using the prime factorization of each number. It would be faster for this question, but it's harder to understand and remember.
The LCM is 120.
LCM(8, 10, 12) = 120.
LCM(8, 12, 10) = 120.
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
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 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.
The Least Common Multiple (LCM) for 15 10 12 8 is 120.
The LCM is: 360
