A palindrome number is a number that is the same forwards as backwards. Some examples are 3443, 12321, and 59095.
Here's my question: What is the largest 12 digit palindrome that is evenly divisible by 7?

It would appear that the largest 12 digit number, 999,999,999,999 is divisible by 7 and is also a palindrome. So that must be the largest 12 digit palindrome divisible by 7
999,999,999,999 as Stephen mentioned is divisible by 7. Just for fun, here are the next nine largest ones:
999992299999 999989989999 999982289999 999979979999 999972279999 999969969999 999962269999 999959959999 999952259999
If we're not allowing for repeated digits in each half, the largest ten would be:
987654456789** 987634436789 987624426789 987614416789 987604406789 987563365789 987543345789 987523325789 987513315789 987503305789
** = I just find it interesting that in both cases, the largest acceptable answer is unaffected by the "divisible by 7" clause.
