Is 135 a prime or composite number?

Number 135 is not a Prime
135 = 3³ × 5
135 has 8 divisors — 1, 3, 5, 9, 15, 27, 45 and 135; a prime has exactly two: 1 and itself.
Primes up to √135
11² = 121 ≤ 135 < 144 = 12², so it is enough to try primes up to 11
- ÷2 does not divide

135 ÷ 3 = 45 — 3 divides 135, so 135 is composite
Nearest primes: 131 and 137
