Underlined — prime: 3, 11 · 1 — neither prime nor composite · others — composite

Factor pairs of 99

3 pairs: 1 × 99 · 3 × 33 · 9 × 11

Past √99 ≈ 9.95 every pair would repeat one already found — so checking stops at 9.

99 = 3² × 11 → (2 + 1) × (1 + 1) = 6 factors: add 1 to each exponent and multiply.
