    What are the Factors of 155?

    Answer

    Factors of 155:
    1, 5, 31, 155

    4 factors · 155 = 5 × 31 · composite

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

    Factor pairs of 155

    √155 ≈ 12.451531155

    2 pairs: 1 × 155 · 5 × 31

    Past √155 ≈ 12.45 every pair would repeat one already found — so checking stops at 12.

    155 = 5 × 31 → (1 + 1) × (1 + 1) = 4 factors: add 1 to each exponent and multiply.
