2688025

2688025 is a natural number following 2688024 and preceding 2688026. It is an odd, composite integer that is divisible by 5 and 25, reflecting its ending in 25.

Prime factorization and number structure: 2688025 = 25 × 107521. The factor 25 = 5^2 accounts for the ending in 25, while 107521 is prime, giving the full factorization as 5^2 × 107521. Consequently, apart from the square factor 5^2, the number has no repeated primes.

Numerical properties: The sum of digits is 2 + 6 + 8 + 8 + 0 + 2 + 5 = 31, so 2688025 is not divisible by 3 or 9. The number is congruent to 1 modulo 8, modulo 4, and modulo 24, among other small moduli, reflecting its specific residue classes. In base 10, the trailing digits 25 indicate divisibility by 25, and hence by 5^2.

Context and notable aspects: There is no widely recognized special constant or widely cited mathematical object uniquely associated with 2688025. Its most notable simple property is its factorization into 5^2 times a prime, which places it among numbers that are multiples of 25 but not of higher powers of 5.

In summary, 2688025 is a 7-digit integer with a straightforward prime factorization of 5^2 × 107521, where 107521 is prime, making the number composite but only to the extent of the square of 5.
