490000001

490000001 is a natural number that lies in the range of integers used in mathematics and data processing. It is the successor of 490000000 and the predecessor of 490000002, and, like other large integers, it can appear in calculations, datasets, and numerical examples.

In mathematics, 490000001 is an odd integer. It is not divisible by 2 or 5, since it ends in 1. The sum of its digits is 14, so it is not divisible by 3 or 9. A quick divisibility check by 7 shows that 490,000,001 is not a multiple of 7 (since 490,000,000 is divisible by 7, leaving a remainder of 1). A divisibility test by 11 also indicates that it is not divisible by 11 (the alternating sum of its digits is −4, which is not a multiple of 11). Beyond these simple tests, determining whether the number is prime would require a formal primality test or complete factorization.

Usage and context: As a large integer, 490000001 commonly appears as a numeric example, a participant in arithmetic demonstrations, or an identifier in datasets and cataloging systems. It does not correspond to a widely recognized constant, theorem, or public object in the way that numbers like pi or the golden ratio do. Its significance, if any, depends on the specific context in which it is encountered.
