28449

28449 is a natural number that lies between 28448 and 28450. In mathematics, it is a composite number with prime factorization 3^2 × 29 × 109, meaning it is the product of 9, 29, and 109.

The positive divisors of 28449 are 1, 3, 9, 29, 87, 109, 261, 327, 981, 3161, 9483, and 28449. This reflects its factorization into 3^2, 29, and 109, giving a total of 12 divisors. The number is odd and divisible by 9 (the digits sum to 27, and 28449/9 = 3161).

28449 is not a perfect square, since its prime factorization includes primes (29 and 109) with exponent 1. It is also not a triangular number; solving n(n+1)/2 = 28449 yields a non-integer n, so 28449 does not occupy a triangular position in the sequence of triangular numbers. The digital root of 28449 is 9, reflecting its divisibility by 9.

A compact way to express its structure is 28449 = 9 × 3161, with 3161 itself equal to 29 × 109. Beyond these basic arithmetic properties, 28449 does not have widely known special significance in standard mathematical sequences or notable historical references.
