    What are the Factors of 1,420?

    Answer

    Factors of 1,420:
    1, 2, 4, 5, 10, 20, 71, 142, 284, 355, 710, 1420

    12 factors · 1420 = 22 × 5 × 71 · composite

    Underlined — prime: 2, 5, 71 · 1 — neither prime nor composite · others — composite

    Factor pairs of 1,420

    • 1 × 1420
    • 2 × 710
    • 4 × 355
    • 5 × 284
    • 10 × 142
    • 20 × 71

    √1420 ≈ 37.68 — the last pair 20 × 71 sits here; past it pairs repeat.
