    1,780,000 = 2⁵ × 5⁴ × 89

    1,780,000 has 60 divisors, not two: a prime is divisible only by 1 and itself.

    Primes up to √1,780,000

    1,334² = 1,779,556 ≤ 1,780,000 < 1,782,225 = 1,335², so it is enough to try primes up to 1,334

    • ÷2 divides

    1,780,000 ÷ 2 = 890,000 — 2 divides 1,780,000, so 1,780,000 is composite
