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 26,893,009, 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 | 26,893,009 | |
| -1 | -26,893,009 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,893,009.
Example:
1 x 26,893,009 = 26,893,009
and
-1 x -26,893,009 = 26,893,009
Notice both answers equal 26,893,009
With that explanation out of the way, let's continue. Next, we take the number 26,893,009 and divide it by 2:
26,893,009 ÷ 2 = 13,446,504.5
If the quotient is a whole number, then 2 and 13,446,504.5 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 | 26,893,009 | |
| -1 | -26,893,009 |
Now, we try dividing 26,893,009 by 3:
26,893,009 ÷ 3 = 8,964,336.3333
If the quotient is a whole number, then 3 and 8,964,336.3333 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 | 26,893,009 | |
| -1 | -26,893,009 |
Let's try dividing by 4:
26,893,009 ÷ 4 = 6,723,252.25
If the quotient is a whole number, then 4 and 6,723,252.25 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 | 26,893,009 | |
| -1 | 26,893,009 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 61 | 143 | 671 | 793 | 3,083 | 8,723 | 33,913 | 40,079 | 188,063 | 440,869 | 2,068,693 | 2,444,819 | 26,893,009 |
| -1 | -11 | -13 | -61 | -143 | -671 | -793 | -3,083 | -8,723 | -33,913 | -40,079 | -188,063 | -440,869 | -2,068,693 | -2,444,819 | -26,893,009 |
