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 26,590,109, 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 | 26,590,109 | |
| -1 | -26,590,109 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,590,109.
Example:
1 x 26,590,109 = 26,590,109
and
-1 x -26,590,109 = 26,590,109
Notice both answers equal 26,590,109
With that explanation out of the way, let's continue. Next, we take the number 26,590,109 and divide it by 2:
26,590,109 ÷ 2 = 13,295,054.5
If the quotient is a whole number, then 2 and 13,295,054.5 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 | 26,590,109 | |
| -1 | -26,590,109 |
Now, we try dividing 26,590,109 by 3:
26,590,109 ÷ 3 = 8,863,369.6667
If the quotient is a whole number, then 3 and 8,863,369.6667 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 | 26,590,109 | |
| -1 | -26,590,109 |
Let's try dividing by 4:
26,590,109 ÷ 4 = 6,647,527.25
If the quotient is a whole number, then 4 and 6,647,527.25 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 | 26,590,109 | |
| -1 | 26,590,109 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 47 | 91 | 329 | 611 | 4,277 | 6,217 | 43,519 | 80,821 | 292,199 | 565,747 | 2,045,393 | 3,798,587 | 26,590,109 |
| -1 | -7 | -13 | -47 | -91 | -329 | -611 | -4,277 | -6,217 | -43,519 | -80,821 | -292,199 | -565,747 | -2,045,393 | -3,798,587 | -26,590,109 |
