Oh, what a happy little question! To find the Least Common Multiple (LCM) of 6, 15, and 21, we look for the smallest number that all three numbers can divide into evenly. First, we list the multiples of each number: 6 (6, 12, 18, 24...), 15 (15, 30, 45...), and 21 (21, 42...). The smallest number they all share is 30, so the LCM of 6, 15, and 21 is 30.
When finding the LCM of three numbers, you first need to break them down into their prime factors:
6 = 2x3
7 = 7
15 = 3x5
The next step is to identify any common factors, and cross off the duplicates. In this case, two numbers have 3 as a factor. Crossing this off leaves us with 2, 3, 5 and 7. Multiply those together and you get 210.
Thus the LCM of 6 7 and 15 is 210.
