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 26,008,645, 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 | 26,008,645 | |
| -1 | -26,008,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,008,645.
Example:
1 x 26,008,645 = 26,008,645
and
-1 x -26,008,645 = 26,008,645
Notice both answers equal 26,008,645
With that explanation out of the way, let's continue. Next, we take the number 26,008,645 and divide it by 2:
26,008,645 ÷ 2 = 13,004,322.5
If the quotient is a whole number, then 2 and 13,004,322.5 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 | 26,008,645 | |
| -1 | -26,008,645 |
Now, we try dividing 26,008,645 by 3:
26,008,645 ÷ 3 = 8,669,548.3333
If the quotient is a whole number, then 3 and 8,669,548.3333 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 | 26,008,645 | |
| -1 | -26,008,645 |
Let's try dividing by 4:
26,008,645 ÷ 4 = 6,502,161.25
If the quotient is a whole number, then 4 and 6,502,161.25 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 | 26,008,645 | |
| -1 | 26,008,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 113 | 565 | 1,469 | 3,541 | 7,345 | 17,705 | 46,033 | 230,165 | 400,133 | 2,000,665 | 5,201,729 | 26,008,645 |
| -1 | -5 | -13 | -65 | -113 | -565 | -1,469 | -3,541 | -7,345 | -17,705 | -46,033 | -230,165 | -400,133 | -2,000,665 | -5,201,729 | -26,008,645 |
