2871

2871 is a natural number that comes after 2870 and before 2872. It is used in mathematics and in various designations where numbers function as identifiers or labels.

In mathematics, 2871 is a composite number. Its prime factorization is 3^2 × 11 × 29, which means it has 12 positive divisors: 1, 3, 9, 11, 29, 33, 87, 99, 261, 319, 957, and 2871. The digit sum of 2871 is 18, so the number is divisible by 3 and by 9. This factorization also shows that 2871 is not a prime, not a square, and not a cube. The presence of multiple small prime factors places it within common discussions of divisor structure and modular arithmetic in number theory.

In broader use, 2871 can appear as a designation or identifier in various fields, including astronomy, where numbered minor planets use consecutive integers as designations. The sequence of such numbers is maintained to identify objects with well-determined orbits, and 2871 would designate the 2871st object in that series.

If encountered in historical or future contexts, 2871 may also be referenced as a year in chronological discussions or speculative fiction, representing a point far beyond the present. As a plain integer, it serves as a data point in arithmetic, algebra, and counting-based applications.
