222430

222430 is a six-digit decimal number that is commonly used as a numerical identifier and in mathematical examples. In base-10 notation it is even and ends with zero.

Factorization and divisibility: 222430 = 2 × 5 × 13 × 29 × 59. The sum of its digits is 13, and the number is divisible by 13, making it a Harshad (Niven) number in base 10. It is also divisible by 10, hence by 2 and 5.

Properties: It is not divisible by 3 or 9, since the digit sum is 13. It has five prime factors listed, giving it a relatively modest divisor count; with prime factors all to the first power, the number of positive divisors is (1+1)^5 = 32.

Usage and context: Beyond pure arithmetic, such numbers often appear as identifiers in catalogs and datasets, such as inventory numbers, model numbers, or catalog references. There is no widely known event centering on this exact value; if used as a designation, it would be unique within its system until the next assigned identifier. The number’s factorization can be of interest in number theory as an example of a product of distinct primes.
