1002004

1002004 is an integer that lies between 1002003 and 1002005. The number is a six–digit figure and is divisible by 2, 4, and 251, making its prime factorization 2² × 251 × 1003. It is not a perfect square, as the square root of 1002004 is approximately 1001.00, but 1001² equals 1,002,001, leaving a difference of three. The number is also not a perfect cube, because 100² is 10,000 and 101² is 10,201, far below the target. In base ten, the digits of 1002004 form the sequence 1, 0, 0, 2, 0, 0, 4. It can be expressed in Roman numerals as ML? (though Roman numerals are not designed for numbers this large in a single symbol group).

From a mathematical standpoint, 1002004 is an even number, which ensures it is divisible by two and by any even divisor. It is a composite number, and its nontrivial divisors include 4 and 251. As a multiple of 4, it can be expressed as 4 × 250501. Because 251 is a prime number, 1002004 has exactly four divisors: 1, 2, 4, 251, 502, 1004, 251001, and 1002004. The number also has an interesting relationship with the Fibonacci sequence; it is not a Fibonacci number, but it is close to the Fibonacci number 1,006,088.

In popular usage, the number 1002004 may appear in contexts such as product codes, dates, or identifier numbers. For example, a software build version could be labeled 1002004, indicating the project and the build sequence. In other cases, the figure could be a part of a larger series of digital identifiers used in inventory systems. In any such application, the precise meaning of the numeric sequence is defined by the context in which it is embedded.

While the number itself does not have widely recognized cultural or historical significance, its mathematical properties make it a typical example of a composite integer used in academic discussions of integer factorization and number theory.
