The firt three multiples of 8 are 8, 16 and 24.
Multiples of 2 are 2, 4, 6, 8, 10, 12, 14, 16, 18, . . . Multiples of 8 are 8, 16, 24, 32, 40, 48, 56, 64, 72, . . .
The first five multiples of 4 are 4, 8, 12, 16 and 20. For them to be common, they need to be compared to another set of multiples.

The common multiples of 4, 8, and 16 are numbers that are divisible by all three of these numbers. To find the common multiples, we first list the multiples of each number: 4 (4, 8, 12, 16, 20, ...), 8 (8, 16, 24, ...), and 16 (16, 32, 48, ...). The common multiples of 4, 8, and 16 are the numbers that appear in all three lists, which are multiples of the least common multiple of 4, 8, and 16, which is 16. Therefore, the common multiples are numbers that are multiples of 16 (16, 32, 48, ...).
