2120

2120 is the integer that follows 2119 and precedes 2121. In mathematics, 2120 is an even composite number. Its prime factorization is 2^3 × 5 × 53, and it has 16 positive divisors. It is divisible by 8, by 5, and by 40, among other divisors. As a Harshad number in base 10, it is divisible by the sum of its digits (2+1+2+0=5), yielding 424. The number 2120 is commonly used in numeric labeling and counting schemes that require four-digit identifiers.

As a calendar year, 2120 CE would be a leap year because it is divisible by 4 and not by 100. It would fall in the 22nd century of the Gregorian calendar, a period spanning 2101–2200. In cultural works, the year 2120 is sometimes used to depict a near-future setting; however, specific plots, technologies, or events depend on the individual work and its authors.

In computing and design contexts, 2120 may appear as a model number or code in product catalogs, inventory systems, or documentation. While the digits themselves do not carry universal meaning beyond their mathematical properties, 2120 serves as an example of a four-digit quantity that is even, composite, and divisible by 40, with a distinct prime factorization.
