    What are the Factors of 1,540?

    Answer

    Factors of 1,540:
    24 factors: 1, 2, 4, 5, 7 … 385, 770, 1540
    all 24 factors

    1, 2, 4, 5, 7, 10, 11, 14, 20, 22, 28, 35, 44, 55, 70, 77, 110, 140, 154, 220, 308, 385, 770, 1540

    24 factors · 1540 = 22 × 5 × 7 × 11 · composite

    Underlined — prime: 2, 5, 7, 11 · 1 — neither prime nor composite · others — composite

    Factor pairs of 1,540

    • 1 × 1540
    • 2 × 770
    • 4 × 385
    • 5 × 308
    • 7 × 220
    • 10 × 154
    • 11 × 140
    • 14 × 110
    • 20 × 77
    • 22 × 70
    • 28 × 55
    • 35 × 44

    √1540 ≈ 39.24 — the last pair 35 × 44 sits here; past it pairs repeat.

    1540 = 22 × 5 × 7 × 11 → (2 + 1) × (1 + 1) × (1 + 1) × (1 + 1) = 24 factors: add 1 to each exponent and multiply.
