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 9,088,805, 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 | 9,088,805 | |
| -1 | -9,088,805 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,088,805.
Example:
1 x 9,088,805 = 9,088,805
and
-1 x -9,088,805 = 9,088,805
Notice both answers equal 9,088,805
With that explanation out of the way, let's continue. Next, we take the number 9,088,805 and divide it by 2:
9,088,805 ÷ 2 = 4,544,402.5
If the quotient is a whole number, then 2 and 4,544,402.5 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 | 9,088,805 | |
| -1 | -9,088,805 |
Now, we try dividing 9,088,805 by 3:
9,088,805 ÷ 3 = 3,029,601.6667
If the quotient is a whole number, then 3 and 3,029,601.6667 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 | 9,088,805 | |
| -1 | -9,088,805 |
Let's try dividing by 4:
9,088,805 ÷ 4 = 2,272,201.25
If the quotient is a whole number, then 4 and 2,272,201.25 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 | 9,088,805 | |
| -1 | 9,088,805 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 257 | 643 | 1,285 | 2,827 | 3,215 | 7,073 | 14,135 | 35,365 | 165,251 | 826,255 | 1,817,761 | 9,088,805 |
| -1 | -5 | -11 | -55 | -257 | -643 | -1,285 | -2,827 | -3,215 | -7,073 | -14,135 | -35,365 | -165,251 | -826,255 | -1,817,761 | -9,088,805 |
