    What are the Factors of 2,005?

    Answer

    Factors of 2,005:
    1, 5, 401, 2005

    4 factors · 2005 = 5 × 401 · composite

    Underlined — prime: 5, 401 · 1 — neither prime nor composite · others — composite

    Factor pairs of 2,005

    √2005 ≈ 44.78154012005

    2 pairs: 1 × 2005 · 5 × 401

    Past √2005 ≈ 44.78 every pair would repeat one already found — so checking stops at 44.

    2005 = 5 × 401 → (1 + 1) × (1 + 1) = 4 factors: add 1 to each exponent and multiply.
