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 26,896,457, 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 | 26,896,457 | |
| -1 | -26,896,457 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,896,457.
Example:
1 x 26,896,457 = 26,896,457
and
-1 x -26,896,457 = 26,896,457
Notice both answers equal 26,896,457
With that explanation out of the way, let's continue. Next, we take the number 26,896,457 and divide it by 2:
26,896,457 ÷ 2 = 13,448,228.5
If the quotient is a whole number, then 2 and 13,448,228.5 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 | 26,896,457 | |
| -1 | -26,896,457 |
Now, we try dividing 26,896,457 by 3:
26,896,457 ÷ 3 = 8,965,485.6667
If the quotient is a whole number, then 3 and 8,965,485.6667 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 | 26,896,457 | |
| -1 | -26,896,457 |
Let's try dividing by 4:
26,896,457 ÷ 4 = 6,724,114.25
If the quotient is a whole number, then 4 and 6,724,114.25 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 | 26,896,457 | |
| -1 | 26,896,457 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 43 | 133 | 301 | 817 | 4,703 | 5,719 | 32,921 | 89,357 | 202,229 | 625,499 | 1,415,603 | 3,842,351 | 26,896,457 |
| -1 | -7 | -19 | -43 | -133 | -301 | -817 | -4,703 | -5,719 | -32,921 | -89,357 | -202,229 | -625,499 | -1,415,603 | -3,842,351 | -26,896,457 |
