There are 3 identical digits in the units period. If the number started with 23 then 2 + 3 = 5 and 20 - 5 = 15 which is divisible by three. If the number started with 24 then 2 + 4 = 6 and 20 - 6 = 14 is not divisible by 3. So the number is 23,000,555.

There is no easy test for divisibility by 7, it is often just as quick, if not quicker, to do the division than any devised test. One test I can suggest: 1) split the number into blocks of 3 digits starting from the right hand end (just like when inserting commas to make a number easier to read); 2) Separately sum the units digits, tens digits and hundreds digits of each block by alternately subtracting and adding starting from the right hand end; 3) Add the sum of the units digits to 3 times the sum of the tens digits to twice the sum of the hundreds digits; 4) if the sum in step 4 is divisible by 7, then so is the original number. got 473: 3 +3×7 + 2×4 = 32 which is not divisible by 7, so 473 is not divisible by 7.
