    What are the Factors of 1,145?

    Answer

    Factors of 1,145:
    1, 5, 229, 1145

    4 factors · 1145 = 5 × 229 · composite

    Underlined — prime: 5, 229 · 1 — neither prime nor composite · others — composite

    Factor pairs of 1,145

    √1145 ≈ 33.84152291145

    2 pairs: 1 × 1145 · 5 × 229

    Past √1145 ≈ 33.84 every pair would repeat one already found — so checking stops at 33.

    1145 = 5 × 229 → (1 + 1) × (1 + 1) = 4 factors: add 1 to each exponent and multiply.
