Is 282 a prime or composite number?

Answer

Number 282 is not a Prime

282 = 2 × 3 × 47

282 has 8 divisors — 1, 2, 3, 6, 47, 94, 141 and 282; a prime has exactly two: 1 and itself.

Primes up to √282

16² = 256 ≤ 282 < 289 = 17², so it is enough to try primes up to 16

÷2 divides

282 ÷ 2 = 141 — 2 divides 282, so 282 is composite

Nearest primes: 281 and 283
