21002000

21002000 is an eight-digit decimal integer. In standard decimal notation it represents twenty-one million two thousand. The sequence may appear as a data identifier, a file name, or a catalog code, rather than as a mathematical constant with a fixed interpretation.

From a mathematical standpoint, 21002000 is an even number and is divisible by 1000. It factors as 21002000 = 21,002 × 1000, and in prime-factor form it can be written as 2^4 × 5^3 × 10501, since 21002 = 2 × 10501. The cofactor 10501 may be prime or composite; its primality is not fixed without further factorization. The number is approximately 2.1 × 10^7.

In data and computing contexts, strings like 21002000 are commonly used as identifiers, serial numbers, or sample values. Their meaning depends entirely on the system that assigns them; there is no universally recognized concept or property tied to the exact sequence 21002000.

If encountered in a dataset, 21002000 could denote anything from an index to a monetary amount in local units, depending on formatting and scale. As a general numeric value, it is an ordinary integer whose significance is determined by external context rather than by intrinsic mathematical characteristics beyond its divisibility and magnitude.
