13218

13218 is a natural number that follows 13217 and precedes 13219. In ordinary arithmetic it is an even number and, due to its digit sum of 15, it is also divisible by 3.

The prime factorization of 13218 is 2 × 3 × 2203, where 2203 is a prime number. This establishes that 13218 is a composite number with exactly eight positive divisors: 1, 2, 3, 6, 2203, 4406, 6609, and 13218.

As a composite integer, 13218 is not a prime, and it is not a perfect square or a perfect cube (since 114^2 = 12996 and 115^2 = 13225, while 13218 lies between them). Its factorization shows it has a simple divisor structure that is useful in basic divisor-count exercises: the number of positive divisors is (1+1)(1+1)(1+1) = 8.

In mathematical contexts, 13218 primarily serves as an example of a small composite integer with a straightforward prime factorization. It does not appear to have any widely recognized special significance in number theory beyond illustrating divisor properties and factorization.
