Is 46 a prime or composite number?

Answer

Number 46 is not a Prime

46 = 2 × 23

46 has 4 divisors — 1, 2, 23 and 46; a prime has exactly two: 1 and itself.

Primes up to √46

6² = 36 ≤ 46 < 49 = 7², so it is enough to try primes up to 6

  • ÷2 divides

46 ÷ 2 = 23 — 2 divides 46, so 46 is composite

Nearest primes: 43 and 47
