The least common multiple (LCM) of 14 and 21 is 42.

To find the least common multiple (LCM) of two numbers, we can list the multiples of each number and find the smallest number that appears in both lists.

Let's start with the multiples of 14: 14, 28, 42, 56, 70, ...

Now, let's list the multiples of 21: 21, 42, 63, 84, 105, ...
