6045

6045 is a natural number that follows 6044 and precedes 6046. In mathematics, it is notable as a composite, squarefree integer with prime factorization 3 × 5 × 13 × 31.

The number is odd and divisible by both 3 and 5, making it a multiple of 15. The sum of its digits is 15, so 6045 is a Harshad (Niven) number in base 10, since 6045 ÷ 15 = 403. Because its prime factors are distinct, 6045 has 16 positive divisors. These divisors are 1, 3, 5, 13, 15, 31, 39, 65, 93, 155, 195, 403, 465, 1209, 2015, and 6045.

As a product of four distinct primes, 6045 is squarefree and therefore not a perfect square or cube. Its factorization also implies it is not a prime power and that its divisor structure is determined by all combinations of the prime factors.

In usage, 6045 can appear as a label, identifier, or numeric code in various systems, such as catalog numbers or data identifiers. It does not correspond to a widely recognized mathematical constant or named object, but its factorization and Harshad property are of general interest in elementary number theory.
