2459 is a natural number that follows 2458 and precedes 2460. It is an odd integer and, in basic number theory, is prime, having no divisors other than 1 and itself. A standard primality check up to the square root of 2459 (about 49.6) shows no divisor among the primes up to 47.

In different numeral systems, 2459 is written as binary 100110011011 and hexadecimal 0x099B. In Roman numerals, it is MMCDLIX.

The digit sum of 2459 is 20, so it is congruent to 2 modulo 9; it is also congruent to 3 modulo 4. As a prime number, it has exactly two positive divisors: 1 and itself, and it cannot be factored into a product of smaller integers.

As a year, 2459 would occur far in the future in the Gregorian calendar. No widely recognized historical events are tied to that year in standard references. Beyond arithmetic and numeral systems, 2459 functions mainly as a label in mathematics and coding, without a single universally defining meaning attached to it.
