18373

18373 is a prime number. It is the 2088th prime number. In decimal representation, it is a palindrome, meaning it reads the same forwards and backward. This property is shared by many prime numbers.

The number 18373 can be expressed as the sum of two squares: 100^2 + 97^2 = 10000 + 9409 = 19409, which is not 18373. However, it can be expressed as the sum of squares in other ways. For example, 18373 = 123^2 + 58^2 = 15129 + 3364 = 18493. This is also incorrect. Let's try again. 18373 = 128^2 + 77^2 = 16384 + 5929 = 22313. This is also incorrect.
