What are the Factors of 55?

Answer

Factors of 55:

1, 5, 11, 55

4 factors · 55 = 5 × 11 · composite

Underlined — prime: 5, 11 · 1 — neither prime nor composite · others — composite

Factor pairs of 55

2 pairs: 1 × 55 · 5 × 11

Past √55 ≈ 7.42 every pair would repeat one already found — so checking stops at 7.

55 = 5 × 11 → (1 + 1) × (1 + 1) = 4 factors: add 1 to each exponent and multiply.
