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 11,626,505, 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 | 11,626,505 | |
| -1 | -11,626,505 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,626,505.
Example:
1 x 11,626,505 = 11,626,505
and
-1 x -11,626,505 = 11,626,505
Notice both answers equal 11,626,505
With that explanation out of the way, let's continue. Next, we take the number 11,626,505 and divide it by 2:
11,626,505 ÷ 2 = 5,813,252.5
If the quotient is a whole number, then 2 and 5,813,252.5 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 | 11,626,505 | |
| -1 | -11,626,505 |
Now, we try dividing 11,626,505 by 3:
11,626,505 ÷ 3 = 3,875,501.6667
If the quotient is a whole number, then 3 and 3,875,501.6667 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 | 11,626,505 | |
| -1 | -11,626,505 |
Let's try dividing by 4:
11,626,505 ÷ 4 = 2,906,626.25
If the quotient is a whole number, then 4 and 2,906,626.25 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 | 11,626,505 | |
| -1 | 11,626,505 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 137 | 685 | 1,507 | 1,543 | 7,535 | 7,715 | 16,973 | 84,865 | 211,391 | 1,056,955 | 2,325,301 | 11,626,505 |
| -1 | -5 | -11 | -55 | -137 | -685 | -1,507 | -1,543 | -7,535 | -7,715 | -16,973 | -84,865 | -211,391 | -1,056,955 | -2,325,301 | -11,626,505 |
