200000001

200000001 is a positive integer in the decimal numeral system, equal to two hundred million and one. It is a nine-digit number that can appear in arithmetic examples and computer science contexts where large integers are discussed.

In mathematics, 200000001 is composite. Its prime factorization begins with 3, since the sum of its digits is 3, indicating divisibility by 3. Specifically, 200000001 = 3 × 66666667. The cofactor 66666667 is odd and not divisible by 2 or 5, and its primality is not immediately evident from this factorization alone. Beyond this, no simple small-factor decomposition is generally noted, so the number serves as a straightforward example of a large composite that is not a power of a small prime.

From a computational perspective, 200000001 lies between 2^27 and 2^28, so it requires 28 bits to represent in binary. It is well within the range of a 32-bit signed integer, which spans from −2,147,483,648 to 2,147,483,647, making it a typical value for testing algorithms and data structures that handle large integers.

Overall, 200000001 is primarily of interest as a large composite with a simple factorization and as a representative example in discussions of divisibility and integer representation, rather than as a notable constant or sequence.
