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 26,665,685, 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 | 26,665,685 | |
| -1 | -26,665,685 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,665,685.
Example:
1 x 26,665,685 = 26,665,685
and
-1 x -26,665,685 = 26,665,685
Notice both answers equal 26,665,685
With that explanation out of the way, let's continue. Next, we take the number 26,665,685 and divide it by 2:
26,665,685 ÷ 2 = 13,332,842.5
If the quotient is a whole number, then 2 and 13,332,842.5 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 | 26,665,685 | |
| -1 | -26,665,685 |
Now, we try dividing 26,665,685 by 3:
26,665,685 ÷ 3 = 8,888,561.6667
If the quotient is a whole number, then 3 and 8,888,561.6667 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 | 26,665,685 | |
| -1 | -26,665,685 |
Let's try dividing by 4:
26,665,685 ÷ 4 = 6,666,421.25
If the quotient is a whole number, then 4 and 6,666,421.25 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 | 26,665,685 | |
| -1 | 26,665,685 |
If you did it right, you will end up with this table:
| 1 | 5 | 47 | 233 | 235 | 487 | 1,165 | 2,435 | 10,951 | 22,889 | 54,755 | 113,471 | 114,445 | 567,355 | 5,333,137 | 26,665,685 |
| -1 | -5 | -47 | -233 | -235 | -487 | -1,165 | -2,435 | -10,951 | -22,889 | -54,755 | -113,471 | -114,445 | -567,355 | -5,333,137 | -26,665,685 |
