It is well known that if the digits of a number add to a multiple of 3 then so does the number (the same property holds for 9). We look for a number such that
2_ _ is a minimum, and divides 9

so we can see the least number possible must be 207

---------------
The 3 is superfluous. If it's divisible by 9 it's divisible by 3.
--> 207
