Is 10,000 a prime or composite number?
Answer
Number 10,000 is not a Prime
10,000 = 2⁴ × 5⁴
10,000 has 25 divisors, not two: a prime is divisible only by 1 and itself. It is a perfect square.
Primes up to √10,000
100² = 10,000 ≤ 10,000 < 10,201 = 101², so it is enough to try primes up to 100
- ÷2 divides
10,000 ÷ 2 = 5,000 — 2 divides 10,000, so 10,000 is composite
Nearest primes: 9,973 and 10,007
