2893

2893 is a natural number that follows 2892 and precedes 2894. It is an odd, composite integer with prime factorization 11 × 263, where both 11 and 263 are prime. Consequently, 2893 is square-free, since its prime factors are distinct.

The sum of its decimal digits is 2 + 8 + 9 + 3 = 22, and the number is divisible by 11, as indicated by the alternating-sum test (2 − 8 + 9 − 3 = 0). In Roman numerals, 2893 is written as MMDCCCXCIII, reflecting 2000 (MM) plus 800 (DCCC) plus 90 (XC) plus 3 (III).

In mathematical contexts, 2893 is not prime or a power, but it serves as an example of a composite, square-free number, being the product of two distinct primes. Its residue classes include 2893 ≡ 1 (mod 3), 2893 ≡ 1 (mod 4), and 2893 ≡ 5 (mod 8).

If used in calendar notation as a year, 2893 AD would fall in the distant future, within the third millennium; no widely noted historical events are associated with that year.
