    What are the Factors of 2,015?

    Answer

    Factors of 2,015:
    1, 5, 13, 31, 65, 155, 403, 2015

    8 factors · 2015 = 5 × 13 × 31 · composite

    Underlined — prime: 5, 13, 31 · 1 — neither prime nor composite · others — composite

    Factor pairs of 2,015

    √2015 ≈ 44.89151331651554032015

    4 pairs: 1 × 2015 · 5 × 403 · 13 × 155 · 31 × 65

    Past √2015 ≈ 44.89 every pair would repeat one already found — so checking stops at 44.

    2015 = 5 × 13 × 31 → (1 + 1) × (1 + 1) × (1 + 1) = 8 factors: add 1 to each exponent and multiply.
