Is 226 a prime or composite number?

Answer

Number 226 is not a Prime

226 = 2 × 113

226 has 4 divisors — 1, 2, 113 and 226; a prime has exactly two: 1 and itself.

Primes up to √226

15² = 225 ≤ 226 < 256 = 16², so it is enough to try primes up to 15

÷2 divides

226 ÷ 2 = 113 — 2 divides 226, so 226 is composite

Nearest primes: 223 and 227
