What are the Factors of 402?

Answer

Factors of 402:
1, 2, 3, 6, 67, 134, 201, 402

8 factors · 402 = 2 × 3 × 67 · composite

Underlined — prime: 2, 3, 67 · 1 — neither prime nor composite · others — composite

Factor pairs of 402

√402 ≈ 20.05123667134201402

4 pairs: 1 × 402 · 2 × 201 · 3 × 134 · 6 × 67

Past √402 ≈ 20.05 every pair would repeat one already found — so checking stops at 20.

402 = 2 × 3 × 67 → (1 + 1) × (1 + 1) × (1 + 1) = 8 factors: add 1 to each exponent and multiply.
