    What are the Factors of 404?

    Answer

    Factors of 404:
    1, 2, 4, 101, 202, 404

    6 factors · 404 = 22 × 101 · composite

    Underlined — prime: 2, 101 · 1 — neither prime nor composite · others — composite

    Factor pairs of 404

    √404 ≈ 20.10124101202404

    3 pairs: 1 × 404 · 2 × 202 · 4 × 101

    Past √404 ≈ 20.10 every pair would repeat one already found — so checking stops at 20.

    404 = 22 × 101 → (2 + 1) × (1 + 1) = 6 factors: add 1 to each exponent and multiply.
