730000

730000, written as 730,000, is the six-digit integer equal to seven hundred thirty thousand in the decimal system. It can be expressed as 730000 = 73 × 10,000, and in prime factorization as 2^4 × 5^4 × 73. The number is even and ends in four zeros, indicating divisibility by 10,000; indeed 730000 / 10,000 = 73.

Its digit sum is 7 + 3 + 0 + 0 + 0 + 0 = 10, so 730000 is a Harshad (Niven) number in base 10, since it is divisible by the sum of its digits. In scientific notation, 730000 is written as 7.3 × 10^5. It is also equal to 730 thousand or 73 × 10^4.

In terms of magnitude, 730000 lies between 700,000 and 760,000. As a round figure, it is commonly used as an approximation in statistics, budgeting, and other quantitative contexts where precise detail is unnecessary. The combination of a small prime factorization (73) with large powers of 2 and 5 makes it a convenient example of a composite, highly factorable number in base 10 arithmetic.
