Answer

Factors of 70:

1, 2, 5, 7, 10, 14, 35, 70

Underlined — prime: 2, 5, 7 · 1 — neither prime nor composite · others — composite

Factor pairs of 70

4 pairs: 1 × 70 · 2 × 35 · 5 × 14 · 7 × 10

Past √70 ≈ 8.37 every pair would repeat one already found — so checking stops at 8.

70 = 2 × 5 × 7 → (1 + 1) × (1 + 1) × (1 + 1) = 8 factors: add 1 to each exponent and multiply.
