499999999997

499999999997 is an integer in the decimal numeral system, equal to 499,999,999,997. It can be expressed as 5×10^11 − 3, making it a 12-digit, odd number near the 5×10^11 scale. Because it ends in 7, it is not divisible by 2 or 5.

From a basic arithmetic standpoint, the sum of its digits is 101, so the number is not divisible by 3 or 9. Using the divisibility test for 11, placing the digits in alternating sums from right to left yields 52 for the odd-position sum and 49 for the even-position sum; their difference is 3, so the number is not divisible by 11. The number is thus coprime to 2, 3, 5, and 11, though primality cannot be concluded from these tests alone.

In binary, 499999999997 has a bit-length of 39, since it lies between 2^38 and 2^39. It easily fits within 64-bit integer representations used by most programming languages. Its value places it in the upper range of 12-digit integers and near the limit where simple exact arithmetic tests become impractical, necessitating more advanced primality tests for definitive factorization status.

There is no widely noted special significance attached to this specific value beyond its role as a near-5×10^11 example, and it can be used in illustrative contexts involving large integers, modular arithmetic, or computer science discussions about 64-bit computations. Related nearby numbers include 500000000000 and 499999999996.
