14509

14509 is a natural number that follows 14508 and precedes 14510. It is an odd five-digit integer and, as a standalone value, has no widely recognized meaning beyond its use in arithmetic and number theory.

In mathematics, 14509 has the prime factorization 11 × 1319. The quotient 1319 is prime, so 14509 is a semiprime (a product of two prime numbers). The divisibility by 11 can be verified by the standard test: taking the alternating sum of digits from the right (9 + 5 + 1) − (0 + 4) = 11, which is a multiple of 11.

Further numerical properties include that the sum of its digits is 19, so 14509 is not divisible by 3, and its value modulo 4 is 1, since it ends in 09 and 14509 ≡ 1 (mod 4). These attributes place 14509 among composite integers with two prime factors, contributing modestly to discussions of semiprimes and their distribution.
