528725

528725 is a six-digit natural number. It is an odd composite number that lies between 528724 and 528726. In arithmetic terms, it has a simple prime factorization and a small set of divisors.

Its prime factorization is 25 × 21149, which can be written as 5^2 × 21149. Because 21149 is (as far as standard small-prime tests indicate) prime and is relatively prime to 5, the complete set of divisors of 528725 is 1, 5, 25, 21149, 105745 (which is 21149 × 5), and 528725 itself. The number is thus not square-free due to the square factor 5^2.

In terms of basic digit properties, the sum of its digits is 29, so it is not divisible by 3. It ends in 25, which confirms divisibility by 25. The last two digits being 25 also implies the number is congruent to 1 modulo 4.
