Answer

Factors of 228:
1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228

12 factors · 228 = 22 × 3 × 19 · composite

Underlined — prime: 2, 3, 19 · 1 — neither prime nor composite · others — composite

Factor pairs of 228

  • 1 × 228
  • 2 × 114
  • 3 × 76
  • 4 × 57
  • 6 × 38
  • 12 × 19

√228 ≈ 15.10 — the last pair 12 × 19 sits here; past it pairs repeat.

228 = 22 × 3 × 19 → (2 + 1) × (1 + 1) × (1 + 1) = 12 factors: add 1 to each exponent and multiply.
