  - **12** (factors: 1, 2, 3, 4, 6, 12)
  - **15** (factors: 1, 3, 5, 15)
  - **20** (factors: 1, 2, 4, 5, 10, 20)
  - **24** (factors: 1, 2, 3, 4, 6, 8, 12, 24)
  - **30** (factors: 1, 2, 3, 5, 6, 10, 15, 30)
  - **40** (factors: 1, 2, 4, 5, 8, 10, 20, 40)
  - **60** (factors: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60)
  - **120** (factors: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120)

*Note:* The numbers **1**, **2**, **3**, and **5** are **not** composite:
