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 26,687,089, 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 | 26,687,089 | |
| -1 | -26,687,089 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,687,089.
Example:
1 x 26,687,089 = 26,687,089
and
-1 x -26,687,089 = 26,687,089
Notice both answers equal 26,687,089
With that explanation out of the way, let's continue. Next, we take the number 26,687,089 and divide it by 2:
26,687,089 ÷ 2 = 13,343,544.5
If the quotient is a whole number, then 2 and 13,343,544.5 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 | 26,687,089 | |
| -1 | -26,687,089 |
Now, we try dividing 26,687,089 by 3:
26,687,089 ÷ 3 = 8,895,696.3333
If the quotient is a whole number, then 3 and 8,895,696.3333 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 | 26,687,089 | |
| -1 | -26,687,089 |
Let's try dividing by 4:
26,687,089 ÷ 4 = 6,671,772.25
If the quotient is a whole number, then 4 and 6,671,772.25 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 | 26,687,089 | |
| -1 | 26,687,089 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 143 | 431 | 433 | 4,741 | 4,763 | 5,603 | 5,629 | 61,633 | 61,919 | 186,623 | 2,052,853 | 2,426,099 | 26,687,089 |
| -1 | -11 | -13 | -143 | -431 | -433 | -4,741 | -4,763 | -5,603 | -5,629 | -61,633 | -61,919 | -186,623 | -2,052,853 | -2,426,099 | -26,687,089 |
