    What are the Factors of 172?

    Answer

    Factors of 172:
    1, 2, 4, 43, 86, 172

    6 factors · 172 = 22 × 43 · composite

    Underlined — prime: 2, 43 · 1 — neither prime nor composite · others — composite

    Factor pairs of 172

    √172 ≈ 13.111244386172

    3 pairs: 1 × 172 · 2 × 86 · 4 × 43

    Past √172 ≈ 13.11 every pair would repeat one already found — so checking stops at 13.

    172 = 22 × 43 → (2 + 1) × (1 + 1) = 6 factors: add 1 to each exponent and multiply.
