5489

5489 is a natural number that follows 5488 and precedes 5490. In mathematics, it is notable as a semiprime: its prime factorization is 11 × 499, where both 11 and 499 are prime. Consequently, 5489 has exactly four positive divisors: 1, 11, 499, and 5489.

Representations in other bases include binary 1010101110001, hexadecimal 0x1571, and octal 12561.

Numerically, 5489 is odd and not divisible by 3 or 5; its digit sum is 26. It is congruent to 1 modulo 4 and is divisible by 11 and 499. Because both prime factors are congruent to 3 modulo 4, 5489 is not a sum of two squares.

In number theory, semiprimes such as 5489 are often used as simple examples in discussions of factoring and primality. They illustrate the idea that a composite number can have multiple, distinct prime factors and a small number of divisors.

There is no widely recognized historical or cultural significance attached to 5489 beyond its role as a small semiprime, and it does not function as a standard constant or identifier in common mathematical references.
