What are the Factors of 36?

Answer

Factors of 36:

1, 2, 3, 4, 6, 9, 12, 18, 36

9 factors · 36 = 2² × 3² · composite

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

Factor pairs of 36

5 pairs: 1 × 36 · 2 × 18 · 3 × 12 · 4 × 9 · 6 × 6

6 × 6 is a pair of one factor — that is why 36 has an odd number of factors, 9.

36 = 2² × 3² → (2 + 1) × (2 + 1) = 9 factors: add 1 to each exponent and multiply.
