16817

16817 is a natural number that sits between 16816 and 16818. It is an odd composite number rather than a prime, and it has a distinct factorization that places it within ordinary arithmetic study rather than prime-focused contexts.

Its prime factorization is 16817 = 67 × 251, with 67 and 251 both prime. Because it is the product of two distinct primes, 16817 has exactly four positive divisors: 1, 67, 251, and 16817. This makes it a semiprime and a squarefree number.

In terms of size and divisor sums, 16817 is a deficient number. The sum of its proper divisors is 1 + 67 + 251 = 319, which is far smaller than 16817. The total sum of divisors is sigma(16817) = (1 + 67)(1 + 251) = 68 × 252 = 17136, giving an abundancy index of sigma(n)/n = 17136/16817 ≈ 1.019.

Representations of 16817 include decimal 16817, hexadecimal 0x41B1, and octal 40661. In binary, 16817 is 100000110110001 when written with 15 bits (or 0100000110110001 in a 16-bit form). These representations reflect its factorization and position within base systems commonly used in mathematics and computing.
