Answer

Factors of 805:

1, 5, 7, 23, 35, 115, 161, 805

8 factors · 805 = 5 × 7 × 23 · composite

Underlined — prime: 5, 7, 23 · 1 — neither prime nor composite · others — composite

Factor pairs of 805

4 pairs: 1 × 805 · 5 × 161 · 7 × 115 · 23 × 35

Past √805 ≈ 28.37 every pair would repeat one already found — so checking stops at 28.

805 = 5 × 7 × 23 → (1 + 1) × (1 + 1) × (1 + 1) = 8 factors: add 1 to each exponent and multiply.
