Find the Least Common Multiple of a list of numbers.
What is the LCM?
O Least Common Multiple (LCM)of two or more numbers is the smallest positive integer that is a multiple of all of them at the same time.
Practical Example:
What is the LCM of 4 and 6?
- The multiples of 4 are: 4, 8,12, 16, 20...
- The multiples of 6 are: 6,12, 18, 24...
The smallest number that appears in both lists is 12. Therefore, the LCM of 4 and 6 is 12.
What is the practical use of the LCM?
The LCM is essential for adding or subtracting fractions that have different denominators. It is also widely used in everyday problems to find out when two cyclic events will happen at the same time again (e.g., \"if a bus comes every 15 minutes and another every 20 minutes, how long will it take for them to come together?\").
