    What are the Factors of 2,445?

    Answer

    Factors of 2,445:
    1, 3, 5, 15, 163, 489, 815, 2445

    8 factors · 2445 = 3 × 5 × 163 · composite

    Underlined — prime: 3, 5, 163 · 1 — neither prime nor composite · others — composite

    Factor pairs of 2,445

    √2445 ≈ 49.45135151634898152445

    4 pairs: 1 × 2445 · 3 × 815 · 5 × 489 · 15 × 163

    Past √2445 ≈ 49.45 every pair would repeat one already found — so checking stops at 49.

    2445 = 3 × 5 × 163 → (1 + 1) × (1 + 1) × (1 + 1) = 8 factors: add 1 to each exponent and multiply.
