13333

13333 is a natural number that lies between 13332 and 13334. It is an odd composite number.

Its prime factorization is 67 × 199, making 13333 a semiprime. As a result, it has exactly four positive divisors: 1, 67, 199, and 13333. The sum of its digits is 13, so it is not divisible by 3. The number is not a square or a cube, and its decimal representation contains four consecutive identical digits after the leading 1 (13333).

In mathematical discussions, 13333 is often cited as an example of a semiprime with relatively large prime factors. The number is relatively small in magnitude (on the order of ten-thousands) but notable for its factorization into two distinct primes. Beyond its factorization properties and digit pattern, 13333 does not have a widely recognized mathematical or historical significance. It can be used in examples illustrating divisors, prime factorization, and digit-based properties within introductory number theory.
