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 each of the given numbers. Here are the calculations for the three cases you provided:

1. LCM of 3 and 5: The multiples of 3: 3, 6, 9, 12, 15, 18, 21, ... The multiples of 5: 5, 10, 15, 20, 25, 30, ... The least common multiple of 3 and 5 is 15.

2. LCM of 15 and 20: The multiples of 15: 15, 30, 45, 60, ... The multiples of 20: 20, 40, 60, 80, ... The least common multiple of 15 and 20 is 60.

3. LCM of 42 and 60: The multiples of 42: 42, 84, 126, 168, 210, ... The multiples of 60: 60, 120, 180, 240, ... The least common multiple of 42 and 60 is 420.

So, the least common multiples are:

1. LCM(3, 5) = 15
2. LCM(15, 20) = 60
3. LCM(42, 60) = 420
