2244

2244 is the natural number that follows 2243 and precedes 2245. In mathematics, it is an even composite number with prime factorization 2^2 × 3 × 11 × 17. This factorization shows that 2244 is divisible by 4, 3, 11, and 17, among other divisors. The sum of all its divisors is 6048, which means 2244 is an abundant number because the sum of its proper divisors (6048 minus 2244) equals 3804, exceeding the number itself. Additionally, since the sum of its digits is 12, 2244 is a Harshad (Niven) number in base 10, meaning it is divisible by the sum of its digits.

In calendar terms, the year 2244 in the Gregorian calendar is a leap year, as it is divisible by 4 and is not a century year. This results in February having 29 days and the year containing 366 days in total. Being a far-future year, 2244 has appeared in speculative fiction and theoretical discussions about long-term planning or astronomical events, but it does not correspond to any widely recorded historical occurrence.

In number theory, 2244 is typically cited as an example of an abundant number and a Harshad number. It is used to illustrate how a single integer can exhibit multiple interesting properties related to its divisors, digit sum, and base-10 representation.
