16449

16449 is a natural number that lies between 16448 and 16450. In decimal notation it is written as 16449 and is classified as an odd composite integer.

Its prime factorization is 3 × 5483, with 5483 being prime. As a result, 16449 has exactly four positive divisors: 1, 3, 5483, and 16449. The digits sum to 24, so the number is divisible by 3 but not by 9. It is not a perfect square or cube, and it is congruent to 1 modulo 4.

From a number-theoretic perspective, 16449 is not representable as a sum of two squares. This follows from its prime factorization: the prime 3 (which is congruent to 3 mod 4) appears to an odd power, which prevents such a representation.

In relation to polygonal numbers, 16449 is not a triangular number and not a hexagonal number, as the standard formulas for those sequences do not yield integer solutions for the associated parameters.

Overall, 16449 serves as an example of a small composite integer with a straightforward factorization and a nontrivial digit-sum property, illustrating common properties of integers in basic number theory.
