3895

3895 is a positive integer. Its prime factorization is 5 × 19 × 41, which makes it a composite number with three distinct prime factors and eight divisors in total: 1, 5, 19, 41, 95, 205, 779, and 3895. The Euler totient function yields φ(3895) = 2880, reflecting the count of integers up to 3895 that are relatively prime to it. The number is odd and not a prime power, and it is square-free since no prime factor is repeated.

In various numeral systems, 3895 has these representations: in Roman numerals it can be written as MMMDCCCXCV; in binary it is 111100110111 (which corresponds to 0xF37 in hexadecimal); in octal it is 7467 (0o7467). These representations illustrate how a single integer can appear differently across numeral systems.

There is no widely recognized special significance attached to 3895 in standard mathematical constants or historical dates. It is commonly cited as an example of a number that is the product of three distinct primes, illustrating properties such as a relatively small number of divisors for a three-prime product and a nontrivial totient value.
