Is 284 a prime or composite number?

Answer

Number 284 is not a Prime

284 = 2² × 71

284 has 6 divisors — 1, 2, 4, 71, 142 and 284; a prime has exactly two: 1 and itself.

Primes up to √284

16² = 256 ≤ 284 < 289 = 17², so it is enough to try primes up to 16

  • ÷2 divides

284 ÷ 2 = 142 — 2 divides 284, so 284 is composite

Nearest primes: 283 and 293
