4979

4979 is a natural number that lies between 4978 and 4980. In everyday usage it may serve as a catalog or identification number in various systems, from astronomy to data sets, or denote a year in far-future chronologies.

In mathematics, 4979 has a simple factorization: 4979 = 13 × 383. This makes it a semiprime, a product of two primes. It is an odd number and is congruent to 3 modulo 4, which has a consequence in number theory: 4979 cannot be expressed as a sum of two integer squares. Its representations in common bases include binary 1001101110011 and hexadecimal 0x1373.

As a plain numeral, 4979 does not carry a special mathematical constant or widely recognized theorem associated with it. Its significance is primarily as an example of a semiprime and as a representative integer in discussions of base representations or modular properties. In practical contexts, it may appear as an identifier in catalogs, inventory systems, or hypothetical calendar references (for instance, a year in a distant future).
