What are the Factors of 75?

Answer

Factors of 75:

1, 3, 5, 15, 25, 75

6 factors · 75 = 3 × 5² · composite

Underlined — prime: 3, 5 · 1 — neither prime nor composite · others — composite

Factor pairs of 75

3 pairs: 1 × 75 · 3 × 25 · 5 × 15

Past √75 ≈ 8.66 every pair would repeat one already found — so checking stops at 8.

75 = 3 × 5² → (1 + 1) × (2 + 1) = 6 factors: add 1 to each exponent and multiply.
