8045

8045 is a natural number that comes after 8044 and before 8046. In arithmetic, 8045 is composite with prime factorization 8045 = 5 × 1609, and 1609 is prime. Therefore, 8045 is a semiprime and not a perfect square. The number is odd and divisible by 5; its digit sum is 17, so it is not divisible by 3 or 9.

Representations of 8045 in common bases include binary, octal, and hexadecimal. In binary it is 1111101101101_2; in octal it is 17555_8; in hexadecimal it is 0x1F6D.

In mathematics, 8045 is often cited as an example of a semiprime and is used in introductory exercises on factorization, modular arithmetic, and base conversion. Its properties as a product of two primes illustrate basic ideas about divisibility and factor structure in the set of natural numbers.

Outside of pure mathematics, 8045 may appear as a model number, catalog identifier, or code in various commercial or technological contexts. However, there is no single widely recognized meaning attached to the number itself beyond its numerical properties.
