Find the least common multiple of 7 and 12.
To find the least common multiple (LCM) of 7 and 12, we need to find the smallest number that is divisible by both 7 and 12.
We can start by listing the multiples of 7: 7, 14, 21, 28, 35, 42, ...
Next, we can list the multiples of 12: 12, 24, 36, 48, ...
Looking at the lists, we can see that the first number that appears in both lists is 84. Therefore, the LCM of 7 and 12 is 84.
