What are the Factors of 30?

Answer

Factors of 30:

1, 2, 3, 5, 6, 10, 15, 30

8 factors · 30 = 2 × 3 × 5 · composite

Underlined — prime: 2, 3, 5 · 1 — neither prime nor composite · others — composite

Factor pairs of 30

4 pairs: 1 × 30 · 2 × 15 · 3 × 10 · 5 × 6

Past √30 ≈ 5.48 every pair would repeat one already found — so checking stops at 5.

30 = 2 × 3 × 5 → (1 + 1) × (1 + 1) × (1 + 1) = 8 factors: add 1 to each exponent and multiply.
