Yes, it is. Your answer is 406. You can determine whether a number is divisible by 3 by adding the digits. If the sum of the digits (in the above, 1+2+1+8 = 12) equals 3, the number is divisible by 3.
The sum of the digits in 252 is 2 + 5 + 2 which equals 9.
If the sum of the digits of a given number equals nine or a multiple of nine, nine is a factor of that number.
There are several hundred of them. One example, the smallest, is 1039
