What are the Factors of 425?

Answer

Factors of 425:

1, 5, 17, 25, 85, 425

6 factors · 425 = 5² × 17 · composite

Underlined — prime: 5, 17 · 1 — neither prime nor composite · others — composite

Factor pairs of 425

3 pairs: 1 × 425 · 5 × 85 · 17 × 25

Past √425 ≈ 20.62 every pair would repeat one already found — so checking stops at 20.

425 = 5² × 17 → (2 + 1) × (1 + 1) = 6 factors: add 1 to each exponent and multiply.
