Answer

Factors of 650:

1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, 650

12 factors · 650 = 2 × 5² × 13 · composite

Underlined — prime: 2, 5, 13 · 1 — neither prime nor composite · others — composite

Factor pairs of 650

6 pairs: 1 × 650 · 2 × 325 · 5 × 130 · 10 × 65 · 13 × 50 · 25 × 26

Past √650 ≈ 25.50 every pair would repeat one already found — so checking stops at 25.

650 = 2 × 5² × 13 → (1 + 1) × (2 + 1) × (1 + 1) = 12 factors: add 1 to each exponent and multiply.
