25001

25001 is a natural number that comes after 25000 and before 25002. In mathematics, it is a composite number with prime factorization 23 × 1087, so it is not prime. Both prime factors are distinct, which makes 25001 square-free.

As a consequence, 25001 is odd and not divisible by 2, 3, or 5 (the sum of its digits is 8). Because its prime factors include 23, which is congruent to 3 modulo 4, 25001 cannot be expressed as a sum of two squares.

It is congruent to 1 modulo 4 and 1 modulo 8 (25001 ≡ 1 (mod 4) and 25001 ≡ 1 (mod 8)). Its binary representation is 110000110101001.

In other contexts, 25001 may appear as a numeric label in lists, catalogs, or identifiers. However, it does not denote a widely recognized mathematical constant, geometric object, or astronomical body on its own.
