13425

13425 is the natural number that follows 13424 and precedes 13426. It is an odd composite number.

Its prime factorization is 3 × 5^2 × 179, with 179 prime. Therefore 13425 is divisible by 3, by 5, by 15, and by 25. In particular, 13425 = 25 × 537 and 537 = 3 × 179, so 13425 = 3 × 5^2 × 179. The total number of positive divisors is (1+1)(2+1)(1+1) = 12.

Written in base 2, 13425 is 11010001110001. In hexadecimal, it is 0x3471.

In base-10, 13425 is a Harshad (or Niven) number, since 1+3+4+2+5 = 15 and 13425 / 15 = 895. This makes 13425 divisible by the sum of its digits, a characteristic shared by Harshad numbers in that base.

As a mathematical object, 13425 is used to illustrate properties of composite numbers with multiple small prime factors, including factorization into distinct primes and the resulting divisor count. Its representations in binary and hexadecimal also demonstrate common bases beyond decimal. While it does not correspond to a widely recognized constant or event, it serves as a concrete example for number-theory discussions and calculations.
