10673

10673 is a natural number. It is odd and composite, with prime factorization 13 × 821. Therefore, it is a semiprime, being the product of exactly two primes.

In various numeral systems, 10673 has these representations: in binary (base 2) it is 10100110110001, and in hexadecimal (base 16) it is 0x29B1. The decimal digits sum to 17, so 10673 is not divisible by 3, and it leaves a remainder of 8 when divided by 9.

10673 is also a sum of two squares in more than one essentially different way. Since 13 = 3^2 + 2^2 and 821 = 14^2 + 25^2, their product can be expressed as a sum of two squares in multiple ways. One representation is 10673 = 92^2 + 47^2 (8464 + 2209). Another is 10673 = 103^2 + 8^2 (10609 + 64). These representations illustrate the classical result that a product of primes congruent to 1 modulo 4 can be written as a sum of two squares in several distinct pairs.

In summary, 10673 is a composite semiprime, factored as 13 × 821, with multiple sum-of-squares representations and recognizable base-2 and base-16 forms.
