Answer 2

To find the least common multiple (LCM) of two or more numbers, you need to determine the smallest multiple that is divisible by all the given numbers. Let's calculate the LCM for the given numbers:

1. LCM(12, 30): To find the LCM of 12 and 30, we can start by listing their multiples: Multiples of 12: 12, 24, 36, 48, 60, ... Multiples of 30: 30, 60, 90, ...

From the list, we can see that 60 is the smallest multiple that is divisible by both 12 and 30. Therefore, LCM(12, 30) = 60.

2. LCM(40, 60): Multiples of 40: 40, 80, 120, ... Multiples of 60: 60, 120, 180, ...

In this case, we can see that 120 is the smallest multiple that is divisible by both 40 and 60. Therefore, LCM(40, 60) = 120.

3. LCM(9, 10): Multiples of 9: 9, 18, 27, 36, 45, ... Multiples of 10: 10, 20, 30, 40, 50, ...

Here, we can see that 90 is the smallest multiple that is divisible by both 9 and 10. Therefore, LCM(9, 10) = 90.

So, the LCMs of the given numbers are: LCM(12, 30) = 60 LCM(40, 60) = 120 LCM(9, 10) = 90
