Is 34 a prime or composite number?

Answer

Number 34 is not a Prime

34 = 2 × 17

34 has 4 divisors — 1, 2, 17 and 34; a prime has exactly two: 1 and itself.

Primes up to √34

5² = 25 ≤ 34 < 36 = 6², so it is enough to try primes up to 5

÷2 divides

34 ÷ 2 = 17 — 2 divides 34, so 34 is composite

Nearest primes: 31 and 37
