Final answer:
To find the least common multiple of 8, 12, and 15, list the multiples of each number and find the smallest common multiple.
Step-by-step explanation:
The least common multiple (LCM) is the smallest multiple that two or more numbers have in common. To find the LCM of 8, 12, and 15, we can start by listing the multiples of each number.
The multiples of 8 are: 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, and so on.
The multiples of 12 are: 12, 24, 36, 48, 60, 72, 84, 96, and so on.
The multiples of 15 are: 15, 30, 45, 60, 75, 90, and so on.
The least common multiple of 8, 12, and 15 is 120. This means that 120 is the smallest number that 8, 12, and 15 all divide evenly into.
