198210

198210 is a six-digit decimal number that can be encountered in various contexts. In date notation, it is commonly interpreted as a compact representation of a calendar month and year in the YYYYMM format, standing for October 1982. This encoding is often used in databases, archives, and financial records to enable straightforward chronological sorting.

Numerical properties of the number include its evenness and its divisibility by 5, as it ends with 0. It is also divisible by 3, since the sum of its digits (1+9+8+2+1+0) equals 21. In terms of factorization, 198210 can be written as 2 × 3 × 5 × 6607; the cofactor 6607 may be prime or composite, and a full factorization would require further testing of 6607.

In addition to date and arithmetic interpretations, 198210 may serve as a generic identifier in various systems, such as a catalog, product code, or entry key. Without specific context, its meaning remains ambiguous beyond its basic numerical properties and its potential to encode a date.

Overall, 198210 illustrates how a single six-digit number can function as both a numeric object with discrete mathematical characteristics and a practical encoding for time in data-management practices.
