783

783 is a natural number that sits between 782 and 784. It is an odd, composite integer with a prime factorization of 3^3 × 29, meaning 783 = 27 × 29. This factorization shows that it is divisible by 3, 9, 27, and 29, as well as by 87 and 261.

The full set of positive divisors of 783 consists of eight numbers: 1, 3, 9, 27, 29, 87, 261, and 783. Consequently, 783 has eight positive divisors in total. Its prime factorization also confirms that 783 is not a perfect square, since the exponents of the prime factors are not all even.

In base-10 arithmetic, 783 is congruent to 0 modulo 3 and modulo 9, reflecting its divisibility by 3 and 9. The digit sum, 7 + 8 + 3 = 18, corroborates this divisibility. Beyond these standard divisibility properties, 783 is primarily of interest as a representative example of a small composite number with a simple prime factorization and a relatively modest divisor count.
