12212 is a natural number that lies between 12211 and 12213. In mathematics, it is an even composite number with a prime factorization of 12212 = 2^2 × 43 × 71.

The number has 12 positive divisors: 1, 2, 4, 43, 71, 86, 142, 172, 284, 3053, 6106, and 12212. The sum of its digits is 1+2+2+1+2 = 8, giving a digital root of 8. In binary, 12212 is represented as 10111110110100_2. In octal, it is 27664_8, and in hexadecimal, it is 2FB4_16. These representations reflect its factorization and place value in different bases.

As a decimal numeral, 12212 appears in ordinary counting and as an example in numeric and computational contexts. It does not have a widely recognized cultural or historical significance beyond its role as a specific integer, though it may occur in catalog numbers, identifiers, or test data just like other five-digit numbers.

Notes on numeric properties include that 12212 is even, composite, and square-free with respect to 2 but not overall due to the prime factors 43 and 71. Its arithmetic characteristics—divisors, base representations, and digit-sum—are typical features studied in elementary number theory.
