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 8,309,105, 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 | 8,309,105 | |
| -1 | -8,309,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,309,105.
Example:
1 x 8,309,105 = 8,309,105
and
-1 x -8,309,105 = 8,309,105
Notice both answers equal 8,309,105
With that explanation out of the way, let's continue. Next, we take the number 8,309,105 and divide it by 2:
8,309,105 ÷ 2 = 4,154,552.5
If the quotient is a whole number, then 2 and 4,154,552.5 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 | 8,309,105 | |
| -1 | -8,309,105 |
Now, we try dividing 8,309,105 by 3:
8,309,105 ÷ 3 = 2,769,701.6667
If the quotient is a whole number, then 3 and 2,769,701.6667 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 | 8,309,105 | |
| -1 | -8,309,105 |
Let's try dividing by 4:
8,309,105 ÷ 4 = 2,077,276.25
If the quotient is a whole number, then 4 and 2,077,276.25 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 | 8,309,105 | |
| -1 | 8,309,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 43 | 215 | 301 | 1,505 | 5,521 | 27,605 | 38,647 | 193,235 | 237,403 | 1,187,015 | 1,661,821 | 8,309,105 |
| -1 | -5 | -7 | -35 | -43 | -215 | -301 | -1,505 | -5,521 | -27,605 | -38,647 | -193,235 | -237,403 | -1,187,015 | -1,661,821 | -8,309,105 |
