Well, honey, the common multiples of 4, 8, and 16 are numbers that all three can divide evenly into. So, the first few common multiples would be 16, 32, 48, and so on. Just keep adding 16 to get more of those bad boys. Happy counting!
80, 160, 240
32, 64, 96
16, 32, 48. Since 16 is divisible by 4. Every multiple of 16 is also a multiple of 4, so I just took the first 3 multiples of 16.
