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 11,425,105, 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 | 11,425,105 | |
| -1 | -11,425,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,425,105.
Example:
1 x 11,425,105 = 11,425,105
and
-1 x -11,425,105 = 11,425,105
Notice both answers equal 11,425,105
With that explanation out of the way, let's continue. Next, we take the number 11,425,105 and divide it by 2:
11,425,105 ÷ 2 = 5,712,552.5
If the quotient is a whole number, then 2 and 5,712,552.5 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 | 11,425,105 | |
| -1 | -11,425,105 |
Now, we try dividing 11,425,105 by 3:
11,425,105 ÷ 3 = 3,808,368.3333
If the quotient is a whole number, then 3 and 3,808,368.3333 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 | 11,425,105 | |
| -1 | -11,425,105 |
Let's try dividing by 4:
11,425,105 ÷ 4 = 2,856,276.25
If the quotient is a whole number, then 4 and 2,856,276.25 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 | 11,425,105 | |
| -1 | 11,425,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 139 | 695 | 967 | 2,363 | 4,835 | 11,815 | 16,439 | 82,195 | 134,413 | 672,065 | 2,285,021 | 11,425,105 |
| -1 | -5 | -17 | -85 | -139 | -695 | -967 | -2,363 | -4,835 | -11,815 | -16,439 | -82,195 | -134,413 | -672,065 | -2,285,021 | -11,425,105 |
