    Is 560 a prime or composite number?

    Answer

    Number 560 is not a Prime

    560 = 2⁴ × 5 × 7

    560 has 20 divisors, not two: a prime is divisible only by 1 and itself.

    Primes up to √560

    23² = 529 ≤ 560 < 576 = 24², so it is enough to try primes up to 23

    • ÷2 divides

    560 ÷ 2 = 280 — 2 divides 560, so 560 is composite

    Nearest primes: 557 and 563
