51825

51825 is a natural number that follows 51824 and precedes 51826. It is an odd, composite integer used in the standard decimal system.

Its prime factorization is 3 × 5^2 × 691, with 691 being a prime number. This makes 51825 divisible by 3, 5, 15, 25, 75, and 691. The sum of its digits is 21, which confirms divisibility by 3 but not by 9, since 21 is not a multiple of 9. The factorization also shows that 51825 is equal to 75 × 691 and to 25 × 2073, illustrating multiple ways to decompose the number into factors.

In other bases, 51825 has the following representations: in hexadecimal it is 0xCA71, and in binary it is 1100101001110001. These representations reflect the same value in different numeral systems and can be useful in fields such as computer science and digital electronics.

From a mathematical perspective, 51825 is not squarefree due to the repeated factor 5 (5^2). It is also not a prime power on its own because it factors into three distinct prime components when considering the full prime decomposition. The number’s factors and representations are straightforward consequences of its composition as 3 × 5^2 × 691.

Overall, 51825 is a representative example of a moderately large, composite integer with a simple prime factorization pattern and standard base representations.
