16685

16685 is a natural number that sits between 16684 and 16686. It is odd and composite, with a prime factorization of 5 × 47 × 71.

It is square-free, since it is the product of three distinct primes. The factorization can be seen by noting that 16685 ends in 5, so it is divisible by 5, and 16685 ÷ 5 = 3337, which factors further as 47 × 71.

As a deficient number, the sum of its proper divisors is 4051, which is less than 16685. The full set of divisors is 1, 5, 47, 71, 235, 355, 3337, and 16685; summing all proper divisors (excluding 16685) yields 4051.

Representations of 16685 include:

- Binary (base 2): 100000100101101

- Octal (base 8): 40455

- Hexadecimal (base 16): 412D

Notable aspects: 16685 is not prime and serves as an example of a square-free, odd, deficient composite with exactly three prime factors. It has limited widespread significance beyond illustrating its factorization and base representations. In number theory, it can be referenced when discussing properties of products of distinct primes and related divisor sum calculations.
