1, 2, 3, 6, 37, 74, 111, 222

8 factors · 222 = 2 × 3 × 37 · composite

Underlined — prime: 2, 3, 37 · 1 — neither prime nor composite · others — composite

Factor pairs of 222

√222 ≈ 14.9012363774111222

4 pairs: 1 × 222 · 2 × 111 · 3 × 74 · 6 × 37

Past √222 ≈ 14.90 every pair would repeat one already found — so checking stops at 14.

222 = 2 × 3 × 37 → (1 + 1) × (1 + 1) × (1 + 1) = 8 factors: add 1 to each exponent and multiply.
