    What are the Factors of 1,840?

    Answer

    Factors of 1,840:
    1, 2, 4, 5, 8, 10, 16, 20, 23, 40, 46, 80, 92, 115, 184, 230, 368, 460, 920, 1840

    20 factors · 1840 = 24 × 5 × 23 · composite

    Underlined — prime: 2, 5, 23 · 1 — neither prime nor composite · others — composite

    Factor pairs of 1,840

    • 1 × 1840
    • 2 × 920
    • 4 × 460
    • 5 × 368
    • 8 × 230
    • 10 × 184
    • 16 × 115
    • 20 × 92
    • 23 × 80
    • 40 × 46

    √1840 ≈ 42.90 — the last pair 40 × 46 sits here; past it pairs repeat.

    1840 = 24 × 5 × 23 → (4 + 1) × (1 + 1) × (1 + 1) = 20 factors: add 1 to each exponent and multiply.
