124999999999

124,999,999,999 is an integer in the decimal numeral system. It is written with 12 digits and is one less than 125,000,000,000, i.e., 125 billion minus one.

Mathematical properties: The number can be expressed as 2^9 × 5^12 − 1. It is odd and not divisible by 2 or 5, since it ends with 9. The sum of its decimal digits is 88, which means it is not divisible by 3 or 9. A divisibility test for 11 yields a nonzero remainder, so it is not a multiple of 11.

Size and representation: In binary, the value lies between 2^36 and 2^37, so it requires 37 bits to represent. It does not have a widely noted representation in terms of a famous constant, though it can be written in hexadecimal or binary for computational purposes.

Context: This number does not correspond to a widely cited constant or theorem. It is a large, ordinary integer that may appear in numerical examples, testing, or data sets where a near-round large decimal value is convenient. As a near-round figure (close to 125 billion), it can be used in demonstrations or benchmarks without carrying any special mathematical significance.
