8915

8915 is a natural number that follows 8914 and precedes 8916. In decimal notation it is written as 8915.

In mathematics, 8915 is a composite number with prime factorization 5 × 1783, where 1783 is prime. Consequently, its divisors are 1, 5, 1783, and 8915. The digit sum is 8 + 9 + 1 + 5 = 23, giving a digital root of 5 and a remainder of 5 when divided by 9. The number is odd and divisible by 5, but not by 3 or 9. Its approximate square root is 94.4, so it is not a perfect square. Because 8915 is congruent to 3 modulo 4, it cannot be expressed as a sum of two squares. In bases other than ten, its representations are 10001011010011 in binary, 0x22D3 in hexadecimal, and 21323 in octal.

From a classificatory perspective, 8915 is not a prime, a power, a triangular number, or a highly notable constant. Its status as a product of two primes (5 and 1783) is its defining simple factorization. The number may appear in various identificatory or cataloging contexts as a four-digit identifier, as is common with many integers in numerical sequences or item numbering systems.

In summary, 8915 is a modest four-digit composite number with factors 5 and 1783, a digital root of 5, and straightforward base representations in binary, octal, and hexadecimal.
