In the multiples of nine, you take the sum of the digits in each number, and you have 9, or another multiple of nine.
Examples:
9 * 6 = 54 ... 5 + 4 = 9
9 * 3 = 27 ... 2 + 7 = 9
9 * 140 = 1260 ... 1 + 2 + 6 + 0 + 9
9 * 487 = 4383 ... 4 + 3 + 8 + 3 = 18 ... 1 + 8 = 9
Yes, they all leave no remainder when divided by 7.
If you are looking for a pattern in the digits, there is one, but it is not simple.
- Partition the number into the units digit, U, and the preceding digits P.
- Calculate P - 2*U
- If the answer is divisible by +/-7 then the original number is a multiple of 7.
- If the answer is too large to test for divisibility by 7 easily then partition the answer and continue.
For example, consider
94675 => P = 9467, U = 5. P - 2*U = 9467 - 10 = 9457.
That may be too large so repeat.
9457 => P = 945, U = 7. P - 2*U = 945 - 14 = 931; still too large.
931 => P = 93, U = 1. P - 2*U = 93 - 2 = 91. 84 = 13*7 so 94668 is a multiple of 7. But you could continue.
91 => P = 9, U = 1. P - 2*U = 9 - 2 = 7 which is obviously a multiple of 7. So the original number is.
Note that the final "answer" can be a negative multiple of 7 or even 0.
The tens digits increase by one, while the ones digits decrease by one.
All digits will add up to 9 when one keeps adding until he/she gets a single digit.
If you sum all the digits in the number and, if the answer is greater than 9, repeat the process again and again, the final answer is 9.
