3219

3219 is a natural number that lies between 3218 and 3220. It is an odd composite number. Its prime factorization is 3 × 29 × 37, which makes it square-free and the product of three distinct primes. Consequently, 3219 is classified as a sphenic number, a term used for integers that are the product of exactly three distinct primes. The positive divisors of 3219 are 1, 3, 29, 37, 87, 111, 1073, and 3219.

In common representations, 3219 is written in binary as 110010010011, in hexadecimal as 0xC93, and in Roman numerals as MMMCCXIX.

The sum of its digits is 15, which is divisible by 3, consistent with its divisibility by 3. The number’s prime factorization also implies it is not a prime, not a perfect square, and not a power of any smaller integer.

In mathematics, 3219 is sometimes cited as an example of a sphenic number and of a composite number with exactly three prime factors, illustrating properties related to factorization and divisor counting. Beyond pure number theory, 3219 may appear in identifiers or cataloging schemes where a numeric label is required, but it does not have a widely recognized significance on its own.
