13915

13915 is a natural number that comes after 13914 and before 13916. In mathematics it is an odd composite integer with a prime factorization of 13915 = 5 × 11^2 × 23. This factorization shows it is not prime and that it includes a squared prime factor (11^2).

As a consequence, 13915 has 12 positive divisors. These divisors are 1, 5, 11, 23, 55, 115, 121, 253, 605, 1265, 2783, and 13915. The presence of the square factor 11^2 explains why the divisor count is 12.

In binary notation, 13915 is 11011001011011₂. In decimal form the number ends with 5, indicating divisibility by 5, and its factorization confirms that it is divisible by 5, 11, and 23. The digits of the decimal representation are 1, 3, 9, 1, and 5, reflecting its composition in base 10.

Beyond general number-theory interest, 13915 serves as an example of how a relatively small integer can have multiple small prime factors and a nontrivial divisor structure, illustrating concepts such as factorization, divisors, and base representations within basic arithmetic.
