Answer

Factors of 273:

1, 3, 7, 13, 21, 39, 91, 273

Factor pairs of 273

4 pairs: 1 × 273 · 3 × 91 · 7 × 39 · 13 × 21

Past √273 ≈ 16.52 every pair would repeat one already found — so checking stops at 16.

273 = 3 × 7 × 13 → (1 + 1) × (1 + 1) × (1 + 1) = 8 factors: add 1 to each exponent and multiply.
