505990

505,990 is a natural number that lies between 505,989 and 505,991. In everyday arithmetic, it is categorized as an even number and a multiple of 10, since its decimal representation ends with a zero.

Its prime factorization can be written as 2 × 5 × 50,599, with 50,599 appearing as the remaining odd factor after dividing by 10. This confirms that 505,990 is not a prime, and it is not a power of a single prime. The number is therefore composite with at least these prime factors.

From a numerical perspective, the square root of 505,990 is approximately 711.4, so the number is not a perfect square. The sum of its digits is 28, which indicates that it is not divisible by 3 or 9. The trailing zero confirms divisibility by 2 and 5, and hence by 10.

Beyond these basic arithmetic properties, 505,990 does not have widely noted mathematical special significance. It serves as a representative example of a large, even composite integer and can be used to illustrate factors, divisibility, and base-ten representation in introductory number theory and arithmetic discussions. As with many integers, its primary role in a wiki-style context is as a concrete object for describing standard properties of numbers rather than as a mathematical constant or cataloged value with additional applied meanings.
