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 8,289,545, 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 | 8,289,545 | |
| -1 | -8,289,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,289,545.
Example:
1 x 8,289,545 = 8,289,545
and
-1 x -8,289,545 = 8,289,545
Notice both answers equal 8,289,545
With that explanation out of the way, let's continue. Next, we take the number 8,289,545 and divide it by 2:
8,289,545 ÷ 2 = 4,144,772.5
If the quotient is a whole number, then 2 and 4,144,772.5 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 | 8,289,545 | |
| -1 | -8,289,545 |
Now, we try dividing 8,289,545 by 3:
8,289,545 ÷ 3 = 2,763,181.6667
If the quotient is a whole number, then 3 and 2,763,181.6667 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 | 8,289,545 | |
| -1 | -8,289,545 |
Let's try dividing by 4:
8,289,545 ÷ 4 = 2,072,386.25
If the quotient is a whole number, then 4 and 2,072,386.25 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 | 8,289,545 | |
| -1 | 8,289,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 23 | 55 | 115 | 253 | 1,265 | 6,553 | 32,765 | 72,083 | 150,719 | 360,415 | 753,595 | 1,657,909 | 8,289,545 |
| -1 | -5 | -11 | -23 | -55 | -115 | -253 | -1,265 | -6,553 | -32,765 | -72,083 | -150,719 | -360,415 | -753,595 | -1,657,909 | -8,289,545 |
