Answer:

198, 396, 594, 792, and 990

Step-by-step explanation:

Multiples of 18: 18, 36, 54, 72, 90, 108, 126, 144, 162, 180, ...

Multiples of 22: 22, 44, 66, 88, 110, 132, 154, 176, 198, 220, ...

Now, let's find the common multiples in these lists:

  • 18 and 22 have common multiples at 198 (18 * 11 = 198)
  • 18 and 22 have common multiples at 396 (18 * 22 = 396)
  • 18 and 22 have common multiples at 594 (18 * 33 = 594)
  • 18 and 22 have common multiples at 792 (18 * 44 = 792)
  • 18 and 22 have common multiples at 990 (18 * 55 = 990)

Therefore, the five common multiples of 18 and 22 are: 198, 396, 594, 792, and 990.
