Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 8,690,429, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 8,690,429 | |
| -1 | -8,690,429 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,690,429.
Example:
1 x 8,690,429 = 8,690,429
and
-1 x -8,690,429 = 8,690,429
Notice both answers equal 8,690,429
With that explanation out of the way, let's continue. Next, we take the number 8,690,429 and divide it by 2:
8,690,429 ÷ 2 = 4,345,214.5
If the quotient is a whole number, then 2 and 4,345,214.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 8,690,429 | |
| -1 | -8,690,429 |
Now, we try dividing 8,690,429 by 3:
8,690,429 ÷ 3 = 2,896,809.6667
If the quotient is a whole number, then 3 and 2,896,809.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 8,690,429 | |
| -1 | -8,690,429 |
Let's try dividing by 4:
8,690,429 ÷ 4 = 2,172,607.25
If the quotient is a whole number, then 4 and 2,172,607.25 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 8,690,429 | |
| -1 | 8,690,429 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 43 | 209 | 473 | 817 | 967 | 8,987 | 10,637 | 18,373 | 41,581 | 202,103 | 457,391 | 790,039 | 8,690,429 |
| -1 | -11 | -19 | -43 | -209 | -473 | -817 | -967 | -8,987 | -10,637 | -18,373 | -41,581 | -202,103 | -457,391 | -790,039 | -8,690,429 |
