230

230 = 2 x 5 x 23.

230 = 2 x 23 x (2 + 3) is the only number with prime factors produced simply from its first two digits, which happen to be the first two primes.

230 is the first number such that it and the next number (231 = 3 x 7 x 11) are both the product of three distinct primes.

230 is the sum of four consecutive squares: 230 = 6² + 7² + 8² + 9².

There are 230 crystal space groups, counting chiral copies as distinct.
