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 8,538,695, 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 | 8,538,695 | |
| -1 | -8,538,695 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,538,695.
Example:
1 x 8,538,695 = 8,538,695
and
-1 x -8,538,695 = 8,538,695
Notice both answers equal 8,538,695
With that explanation out of the way, let's continue. Next, we take the number 8,538,695 and divide it by 2:
8,538,695 ÷ 2 = 4,269,347.5
If the quotient is a whole number, then 2 and 4,269,347.5 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 | 8,538,695 | |
| -1 | -8,538,695 |
Now, we try dividing 8,538,695 by 3:
8,538,695 ÷ 3 = 2,846,231.6667
If the quotient is a whole number, then 3 and 2,846,231.6667 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 | 8,538,695 | |
| -1 | -8,538,695 |
Let's try dividing by 4:
8,538,695 ÷ 4 = 2,134,673.75
If the quotient is a whole number, then 4 and 2,134,673.75 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 | 8,538,695 | |
| -1 | 8,538,695 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 19 | 55 | 95 | 209 | 1,045 | 8,171 | 40,855 | 89,881 | 155,249 | 449,405 | 776,245 | 1,707,739 | 8,538,695 |
| -1 | -5 | -11 | -19 | -55 | -95 | -209 | -1,045 | -8,171 | -40,855 | -89,881 | -155,249 | -449,405 | -776,245 | -1,707,739 | -8,538,695 |
