To find the first three common multiples of the numbers, we need to first determine the least common multiple (LCM) of each pair.
Common Multiples of 6 and 8
1. The multiples of 6 are: 6, 12, 18, 24, 30, 36, 42, …
2. The multiples of 8 are: 8, 16, 24, 32, 40, 48, …
3. The first common multiple is 24, followed by 48, and then 72.
Therefore, the first three common multiples of 6 and 8 are: 24, 48, and 72.
Common Multiples of 12 and 18
1. The multiples of 12 are: 12, 24, 36, 48, 60, 72, …
2. The multiples of 18 are: 18, 36, 54, 72, 90, …
3. The first common multiple is 36, then 72, and the next is 108.
Therefore, the first three common multiples of 12 and 18 are: 36, 72, and 108.
