13655

13655 is a natural number that lies between 13654 and 13656. It is an odd, composite integer, and its prime factorization is 5 × 2731, with 2731 being a prime number. Because it is the product of two primes, 13655 is classified as a semiprime, a type of number of interest in elementary and recreational number theory.

In different bases, 13655 has the following representations: in binary it is 11010101010111, and in hexadecimal it is 0x3557. The decimal form consists of five digits, and the sum of its digits is 20, which means it is not divisible by 3. It is divisible by 5, reflecting its last digit, and the remaining quotient when divided by 5 is 2731.

As a semiprime, 13655 serves as a simple example in discussions of factorization, divisibility, and base representations. It illustrates how a composite number can be expressed as a product of two primes and how such numbers appear across different numeral systems. While 13655 itself does not have known notable historical or scientific significance, it is a useful reference point in educational contexts for exploring prime factorization and numeral bases.
