Answer

Factors of 615:

1, 3, 5, 15, 41, 123, 205, 615

Factor pairs of 615

4 pairs: 1 × 615 · 3 × 205 · 5 × 123 · 15 × 41

Past √615 ≈ 24.80 every pair would repeat one already found — so checking stops at 24.

615 = 3 × 5 × 41 → (1 + 1) × (1 + 1) × (1 + 1) = 8 factors: add 1 to each exponent and multiply.
