Examples
Example 1: Find the LCM of 4, 6 and 12.
Solution:
Start with the three numbers, 4, 6 and 12.
LCM is the product of common and non common factors.
Therefore, LCM(4, 6, 12) = 12.
Example 2: Find the LCM of 10, 12 and 15.
Solution:
Start with the three numbers, 10, 12 and 15.
LCM is the product of common and non common factors.
Therefore, LCM(10, 12, 15) = 60.
Example 3: Find the LCM of 5, 9 and 18.
Solution:
Start with the three numbers, 5, 9 and 18.
LCM is the product of common and non common factors.
Therefore, LCM(5, 9, 18) = 90.
