Multiples of 2 are 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, …
Multiples of 5 are 5, 10, 15, 20, …
Let's represent these multiples on the number line and circle the common multiples,
Thus, the common multiples of 2 and 5 are 10, 20, ….. The smallest number among 10, 20, … is 10. So the least common multiple of 2 and 5 is 10. Therefore, LCM (2, 5) = 10.
