3605

3605 is a natural number that follows 3604 and precedes 3606. In mathematics, it is an odd composite integer with prime factorization 3605 = 5 × 7 × 103. Because the prime factors are distinct, 3605 is square-free and has eight positive divisors: 1, 5, 7, 35, 103, 515, 721, and 3605. It is therefore a 3-almost prime (the product of three primes, counting multiplicity).

Representations and numerals: in base-10, the number is written as 3605. In hexadecimal it is 0xE15; in binary it is 111000010101; in octal it is 7025. In Roman numerals, 3605 is written as MMMDCV.

Numerical context: 3605 is 60^2 + 5, placing it near the square of a round number. Its divisibility by 5 makes it a multiple of a common decimal-ending factor, while its other factors (7 and 103) reflect its nontrivial factorization into three distinct primes. The number’s modest size and factor structure make it a typical example used in discussions of prime factorization, divisor counting, and base-conversion exercises.

Context and usage: as with many integers, 3605 appears in various lists, catalogs, or identifiers across different domains. Without additional context, it functions primarily as a numerical value with the intrinsic properties noted above.
