12455

12455 is a five-digit integer. Its prime factorization is 5 × 47 × 53, making it an odd composite number. The complete set of positive divisors is 1, 5, 47, 53, 235, 265, 2491, and 12455. The sum of its proper divisors (excluding the number itself) is 3097, which is less than 12455, so 12455 is classified as a deficient number in number theory terms.

In postal and data contexts, 12455 is used as a ZIP code in the United States, where five-digit ZIP codes designate mail delivery regions. Beyond mailing, the sequence 12455 can also appear as an identifier in catalogs, inventories, or model numbers, as with many other five-digit numeric codes.

From a mathematical perspective, 12455 is not prime and is not a perfect power; its factorization into 5, 47, and 53 reveals its composite structure. It is an example of how a number can be factored into a product of distinct primes, with corresponding implications for divisor counts and arithmetic properties. As an odd, composite, five-digit number ending in 5, it is divisible by 5 and has multiple nontrivial divisors, illustrating common patterns in integer factorization and divisor arithmetic.
