20000000

Twenty million, written as 20,000,000, is the natural number that comes after 19,999,999 and before 20,000,001. In scientific notation, it is 2 × 10^7, and in words it is twenty million.

In prime factorization terms, 20,000,000 = 2^8 × 5^7, making it a composite number with 72 positive divisors. Since it ends in seven zeros, it is divisible by 10^7 and equals two times 10^7.

As a magnitude, the number is a round decimal figure often used as a benchmark in population counts, financial estimates, and data sizes. For example, 20,000,000 bytes is roughly 19.07 mebibytes (MiB) or about 20 decimal megabytes (MB) depending on whether binary or decimal units are used.

In mathematics and statistics, 20,000,000 serves as a convenient large, round integer for examples, rounding, scaling, and modeling. It is far enough from small integers to illustrate concepts about rate, density, and growth, yet simple enough to compute with easily. The figure also appears in contexts such as census thresholds, funding benchmarks, and capacity planning, where round millions provide a clear sense of scale.

Overall, 20,000,000 is a standard, well-defined quantity in decimal arithmetic, notable for its twofold relationship to powers of ten and its status as a large but tractable round number for practical applications.
