2273

2273 is a natural number that sits between 2272 and 2274. It is an odd integer and, in mathematics, it is a prime number.

Because a prime's primality can be checked by testing divisibility up to the square root, 2273 has no divisors among the primes up to 47. Concretely, it is not divisible by 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, or 47.

In number theory, 2273 is not a Fibonacci, triangular, or square number. It does not correspond to a commonly cited special category of integers such as a Fermat or Mersenne number.

As a calendar year, 2273 CE would be in the 23rd century of the Gregorian calendar; no widely recorded events are associated with that future year in established historical sources.

In other contexts, 2273 can occur as a model or catalog identifier, part number, or code in various datasets. Without additional qualifiers, the meaning of 2273 remains context-dependent and may vary across disciplines or applications.
