What are the Factors of 531?

Answer

Factors of 531:

1, 3, 9, 59, 177, 531

6 factors · 531 = 3² × 59 · composite

Underlined — prime: 3, 59 · 1 — neither prime nor composite · others — composite

Factor pairs of 531

3 pairs: 1 × 531 · 3 × 177 · 9 × 59

Past √531 ≈ 23.04 every pair would repeat one already found — so checking stops at 23.

531 = 3² × 59 → (2 + 1) × (1 + 1) = 6 factors: add 1 to each exponent and multiply.
