12566

12566 is a positive integer that is even and composite. Its prime factorization is 2 × 61 × 103, which gives it eight positive divisors: 1, 2, 61, 103, 122, 206, 6283, and 12566. Because it is the product of three primes (counting multiplicity), 12566 is classified as a 3-almost prime.

The sum of its decimal digits is 20, giving a digital root of 2. As a result, 12566 is not divisible by 3 or 9, and it is not a Harshad (Niven) number in base 10 since 12566 is not divisible by the sum of its digits (20).

In different numeral bases, 12566 has representations commonly cited for reference. In binary, it is 11000100010110₂. In hexadecimal, it is 0x3116. In octal, it is 30426₈. These representations reflect its fixed value across numeral systems and are sometimes used in computing or theoretical exercises to illustrate base conversion.

As a mathematical object, 12566 is a typical example of a small composite number with three distinct prime factors. It does not represent a well-known constant, sequence entry, or special geometric or combinatorial construction on its own, but it can appear in problems involving prime factorizations, divisor counts, and base representations.
