    Is 822 a prime or composite number?

    Answer

    Number 822 is not a Prime

    822 = 2 × 3 × 137

    822 has 8 divisors — 1, 2, 3, 6, 137, 274, 411 and 822; a prime has exactly two: 1 and itself.

    Primes up to √822

    28² = 784 ≤ 822 < 841 = 29², so it is enough to try primes up to 28

    • ÷2 divides

    822 ÷ 2 = 411 — 2 divides 822, so 822 is composite

    Nearest primes: 821 and 823
