10787

10787 is a natural number that follows 10786 and precedes 10788. It is an odd, composite number.

Its prime factorization is 10787 = 7 × 23 × 67, the product of three distinct primes. As a result, 10787 is square-free and has eight positive divisors: 1, 7, 23, 67, 161 (7×23), 469 (7×67), 1541 (23×67), and 10787 (7×23×67).

In terms of arithmetic properties, 10787 is congruent to 3 modulo 4 (10787 mod 4 = 3). The sum of its digits is 23, so it is congruent to 5 modulo 9. Because a prime factor 7 is congruent to 3 modulo 4 and appears to the first power, 10787 cannot be expressed as a sum of two squares.
