To find the common multiples of 2, 3, and 9, we first need to list out the multiples of each number. The multiples of 2 are 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, and so on. The multiples of 3 are 3, 6, 9, 12, 15, 18, 21, 24, 27, and so on. The multiples of 9 are 9, 18, 27, 36, 45, 54, 63, 72, 81, and so on. The first three common multiples of 2, 3, and 9 are 18, 36, and 54.
3
The first three multiples of 3 are 3, 6, 9 The first three multiples of 9 are 9, 18, 27 As the lowest common multiples of 3 and 9 is 9, the common multiples of 3 and 9 are the multiples of 9, thus: The first three common multiples of 3 and 9 are 9, 18, 27
