Outline of Solution
1, i.e. to be able divisible by 7, can be divisible by 9, the result should be divisible by 63.
2, a difference is divisible by 5, then the end of the last 4 or 9. It is not divisible by 2, 4 is not the end, the result should be the last digit 9.
3, only 63 *, 63 * 23 * 13, 63, ..., so the result of the formula in order to make the last digit is 9, so this formula one test down, focus on whether the test results after a reduction by 8 divisible.
4, will soon be able to find 63 * 23 = 1449 is the correct answer.
