320000

320000 is the natural number that follows 319999 and precedes 320001. In decimal notation it is written as 320,000 and is an even, composite number. As a round figure, it often appears in contexts such as population estimates, budgets, or production quantities for towns, projects, or statistical samples.

In mathematics, 320000 has a prime factorization of 2^9 × 5^4, since 320000 = 32 × 10000 and 32 = 2^5 while 10000 = 2^4 × 5^4. This makes the number divisible by 2^9 and by 5^4, and it is a multiple of 1000 and 10,000 as well. The sum of its digits is 3 + 2 + 0 + 0 + 0 + 0 = 5, so it is a Harshad (Niven) number in base 10 because 320000 ÷ 5 = 64000 is an integer.
