180000

180,000 is a natural number that follows 179,999 and precedes 180,001. In scientific notation it is 1.8 × 10^5, and it can be read as one hundred eighty thousand or as 0.18 million.

Prime factorization shows that 180,000 = 2^5 × 3^2 × 5^4. This makes the number even and highly divisible by small primes. Consequently, it is divisible by many integers, including 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, and 25, among others, up to 180,000 itself.

Other properties include its divisibility by 9, since the digit sum is 1 + 8 + 0 + 0 + 0 + 0 = 9. Therefore, 180,000 is a Harshad (Niven) number in base 10. It is also a multiple of 1000 (180,000 = 180 × 1000) and a multiple of 10^4, given the four trailing zeros.

In other bases, 180,000 has distinct representations. In hexadecimal it equals 0x2BF20. This ties the decimal value to a compact alphanumeric form that is often used in computing and digital systems.

Usage and context often reflect its role as a rounded quantity: a common figure for estimates, budgets, or measurements that sit between thousands and millions. As a round number with multiple factors, 180,000 serves as a convenient benchmark in arithmetic, scaling, and quantitative contexts.
