291000

291000 is a natural number that follows 290999 and precedes 291001. In decimal notation it has three trailing zeros, making it a round figure that often appears in measurements, counts, and data sets.

Its prime factorization is 291000 = 2^3 × 3 × 5^3 × 97, which is equivalently 291000 = 97 × 3000. This shows that the number is divisible by 2, 3, 5, 8, and 97, as well as by various products of these primes (for example 12, 15, 20, 25, 75, and 1000). Because it includes the factor 1000, 291000 is a multiple of 1000 and of 10^3.

Additional numeric properties include a digit sum of 12, giving a digital root of 3 and confirming divisibility by 3. The number is also a Harshad (Niven) number in base 10, since it is divisible by the sum of its digits (12) resulting in 24250.

In scientific notation, 291000 equals 2.91 × 10^5. As a six-digit, highly composite-like figure with three zeros, it is commonly used as an example of a large, round quantity in quantitative contexts, such as estimates, budgets, or data summaries. Its factorization highlights a mix of small primes and a relatively large prime factor (97).
