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

6 pairs: 1 × 228 · 2 × 114 · 3 × 76 · 4 × 57 · 6 × 38 · 12 × 19

Past √228 ≈ 15.10 every pair would repeat one already found — so checking stops at 15.

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