    What are the Factors of 381?

    Answer

    Factors of 381:
    1, 3, 127, 381

    4 factors · 381 = 3 × 127 · composite

    Underlined — prime: 3, 127 · 1 — neither prime nor composite · others — composite

    Factor pairs of 381

    √381 ≈ 19.5213127381

    2 pairs: 1 × 381 · 3 × 127

    Past √381 ≈ 19.52 every pair would repeat one already found — so checking stops at 19.

    381 = 3 × 127 → (1 + 1) × (1 + 1) = 4 factors: add 1 to each exponent and multiply.
