235

235 = 5 x 47.

235 has a unique representation as a sum of three squares: 235 = 12 + 32 + 152.

235 is the concatenation of the base 10 representations of the first three primes, and thus a Smarandache-Wellin number.

235 is the smallest number such that the set of its square's digits is a proper subset of the set of its own digits: 2352 = 55225 = (5 + 5 + 225)2.

235 is the smallest number whose first two digits are distinct primes such that their sum equals the third digit.


On average, 19 solar years (228 solar months) is almost exactly
235 lunar months.
