5389

5389 is a natural number that sits between 5388 and 5390. As a four-digit integer, it has several straightforward mathematical properties that make it a useful example in basic number theory.

The prime factorization of 5389 is 17 × 317. Both 17 and 317 are prime, so 5389 is a semiprime—the product of exactly two primes. Consequently, it is composite but not divisible by any small prime other than 17 and 317. Its digits sum to 25, giving a digital root of 7, and it is not a multiple of 3 or 5.

In different numeral systems, 5389 has the following representations: in binary it is 1010100001101, and in hexadecimal it is 0x150D. These representations reflect its decomposition into powers of two and powers of sixteen, respectively.

Geometrically or in abstract algebra, 5389 does not correspond to a widely recognized constant or named quantity. Its significance is mainly in instructional contexts as an example of a semiprime and of how a four-digit number can be expressed in multiple bases.

Usage and occurrence of the number 5389 often appear in cataloging, coding, or numbering schemes where four-digit identifiers are common. Outside of such contexts, there is no widely noted event, object, or theorem specifically associated with the number 5389.
