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 26,531,135, 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 | 26,531,135 | |
| -1 | -26,531,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,531,135.
Example:
1 x 26,531,135 = 26,531,135
and
-1 x -26,531,135 = 26,531,135
Notice both answers equal 26,531,135
With that explanation out of the way, let's continue. Next, we take the number 26,531,135 and divide it by 2:
26,531,135 ÷ 2 = 13,265,567.5
If the quotient is a whole number, then 2 and 13,265,567.5 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 | 26,531,135 | |
| -1 | -26,531,135 |
Now, we try dividing 26,531,135 by 3:
26,531,135 ÷ 3 = 8,843,711.6667
If the quotient is a whole number, then 3 and 8,843,711.6667 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 | 26,531,135 | |
| -1 | -26,531,135 |
Let's try dividing by 4:
26,531,135 ÷ 4 = 6,632,783.75
If the quotient is a whole number, then 4 and 6,632,783.75 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 | 26,531,135 | |
| -1 | 26,531,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 457 | 683 | 2,285 | 3,415 | 7,769 | 11,611 | 38,845 | 58,055 | 312,131 | 1,560,655 | 5,306,227 | 26,531,135 |
| -1 | -5 | -17 | -85 | -457 | -683 | -2,285 | -3,415 | -7,769 | -11,611 | -38,845 | -58,055 | -312,131 | -1,560,655 | -5,306,227 | -26,531,135 |
