8525

8525 is a natural number that lies between 8524 and 8526. It is an odd composite number that appears in mathematical contexts as an example of factorization and divisibility, and it can also serve as a numeric identifier in systems that use codes.

In prime factorization terms, 8525 = 5^2 × 11 × 31. Its positive divisors are 1, 5, 11, 25, 31, 55, 155, 275, 341, 775, 1705, and 8525, for a total of 12 divisors. The number ends with 25 and is therefore a multiple of 25; the digit sum is 20, so it is not divisible by 3 or 9.

Representations in other bases include binary, octal, and hexadecimal. In binary, 8525 is 10000101001101; in octal it is 20515; in hexadecimal it is 0x214D. In Roman numerals, numbers above 3999 are not standard; extended notation would represent 8525 using a vinculum, such as a Bar over the 8000 portion, yielding a form like V̄DXXV to convey 8000 + 500 + 20 + 5.

In practical use, 8525 may appear as a year in future timelines, a product or catalog number, or a code in databases and systems that rely on numeric identifiers. It has no widely cited historical or cultural significance beyond its mathematical properties.
