What are the Factors of 238?

Answer

Factors of 238:
1, 2, 7, 14, 17, 34, 119, 238

8 factors · 238 = 2 × 7 × 17 · composite

Underlined — prime: 2, 7, 17 · 1 — neither prime nor composite · others — composite

Factor pairs of 238

√238 ≈ 15.43127141734119238

4 pairs: 1 × 238 · 2 × 119 · 7 × 34 · 14 × 17

Past √238 ≈ 15.43 every pair would repeat one already found — so checking stops at 15.

238 = 2 × 7 × 17 → (1 + 1) × (1 + 1) × (1 + 1) = 8 factors: add 1 to each exponent and multiply.
