Is 434 a prime or composite number?

Answer

Number 434 is not a Prime

434 = 2 × 7 × 31

434 has 8 divisors — 1, 2, 7, 14, 31, 62, 217 and 434; a prime has exactly two: 1 and itself.

Primes up to √434

20² = 400 ≤ 434 < 441 = 21², so it is enough to try primes up to 20

÷2 divides

434 ÷ 2 = 217 — 2 divides 434, so 434 is composite

Nearest primes: 433 and 439
