249999999997

249999999997 is a natural number. In decimal notation it is 249,999,999,997, a 12-digit odd integer just under 250,000,000,000. It can be described as 250,000,000,000 minus 3, placing it close to a round benchmark in the 2.5×10^11 range.

Mathematically, it is not divisible by 2 or 5, and its digit sum is 94, so it is not divisible by 3. Applying the 11-divisibility test yields a result of zero, which shows that the number is divisible by 11. Indeed, 249,999,999,997 = 11 × 22,727,272,727, so the number is composite.

The cofactor 22,727,272,727 is the remaining factor; its primality is not established here, and further factorization would require additional computation. The presence of the factor 11 demonstrates that the number has a nontrivial divisor, despite its proximity to a round decimal value.
