    What are the Factors of 153?

    Answer

    Factors of 153:
    1, 3, 9, 17, 51, 153

    6 factors · 153 = 32 × 17 · composite

    Underlined — prime: 3, 17 · 1 — neither prime nor composite · others — composite

    Factor pairs of 153

    √153 ≈ 12.371391751153

    3 pairs: 1 × 153 · 3 × 51 · 9 × 17

    Past √153 ≈ 12.37 every pair would repeat one already found — so checking stops at 12.

    153 = 32 × 17 → (2 + 1) × (1 + 1) = 6 factors: add 1 to each exponent and multiply.
