125000000

125000000 is an integer that equals one hundred twenty‑five million in decimal notation. It can be expressed in scientific notation as 1.25×10^8 and uses an eight‑digit numeral. The number is located between 10^8 (100,000,000) and 10^9 (1,000,000,000) and is commonly used as a benchmark in population statistics, economic figures, and scientific measurements where large but manageable quantities are required.

Mathematically, 125000000 has several notable properties. Its prime factorisation is 2^6 × 5^9, which reflects its origin from 10^6 (one million) multiplied by 125 (5^3). Because the exponents of 2 and 5 are different, the number is not a perfect power of a prime, but it is a perfect cube: 500^3 = 125000000. The number is divisible by 10, 100, 1,000, 10,000, 100,000, and 1,000,000, and by 125,000 which yields 1,000. Consequently, it has 120 distinct positive divisors. The sum of its digits is 1, which renders the number a Harshad number in base ten.

In applied contexts, 125000000 often appears as a reference point in demographic reports, such as the approximate population of certain countries in the early twenty‑first century, as a target figure in computational benchmarks, and as a milestone in astronomical datasets where the distance or mass being measured is on the order of 10^8 to 10^9. The numerically simple structure of the number makes it convenient for communication and reporting across disciplines.
