    What are the Factors of 1,625?

    Answer

    Factors of 1,625:
    1, 5, 13, 25, 65, 125, 325, 1625

    8 factors · 1625 = 53 × 13 · composite

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

    Factor pairs of 1,625

    √1625 ≈ 40.31151325651253251625

    4 pairs: 1 × 1625 · 5 × 325 · 13 × 125 · 25 × 65

    Past √1625 ≈ 40.31 every pair would repeat one already found — so checking stops at 40.

    1625 = 53 × 13 → (3 + 1) × (1 + 1) = 8 factors: add 1 to each exponent and multiply.
