    Is 25,000 a prime or composite number?

    Answer

    Number 25,000 is not a Prime

    25,000 = 2³ × 5⁵

    25,000 has 24 divisors, not two: a prime is divisible only by 1 and itself.

    Primes up to √25,000

    158² = 24,964 ≤ 25,000 < 25,281 = 159², so it is enough to try primes up to 158

    • ÷2 divides

    25,000 ÷ 2 = 12,500 — 2 divides 25,000, so 25,000 is composite

    Nearest primes: 24,989 and 25,013
