800000

800000 is the natural number that comes after 799999 and before 800001. It is an even composite number with a prime factorization of 2^8 × 5^5, i.e., 800000 = 256 × 3125. This reflects its role as a product of powers of the primes 2 and 5.

In decimal form, 800000 ends with five zeros, since it equals 8 × 100000 or 8 × 10^5. It is also useful to note its representations in other bases: in binary it is 11000011010100000000, and in hexadecimal it is C3500. In scientific notation it is 8.0 × 10^5.

The number has 54 positive divisors, derived from its prime factorization: (8 + 1) × (5 + 1) = 9 × 6 = 54. It is divisible by 2^8 and by 5^5, and thus by 256 and by 100000, with 800000 = 256 × 3125. The sum of its digits is 8, so in base 10 it is a Harshad (Niven) number because 800000 ÷ 8 = 100000.

In practical terms, 800000 is a common round figure used in statistics, budgeting, population estimates, and capacity planning to denote eight hundred thousand. Its form as a multiple of 10^5 makes it convenient for expressing large-scale quantities without excessive precision, while its factorization highlights its structure as a product of powers of two and five.
