What are the factors of 318?

Answer

Factors of 318:
1, 2, 3, 6, 53, 106, 159, 318

8 factors · 318 = 2 × 3 × 53 · composite

Underlined — prime: 2, 3, 53 · 1 — neither prime nor composite · others — composite

Factor pairs of 318

√318 ≈ 17.83123653106159318

4 pairs: 1 × 318 · 2 × 159 · 3 × 106 · 6 × 53

Past √318 ≈ 17.83 every pair would repeat one already found — so checking stops at 17.

318 = 2 × 3 × 53 → (1 + 1) × (1 + 1) × (1 + 1) = 8 factors: add 1 to each exponent and multiply.
