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 26,085,605, 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 | 26,085,605 | |
| -1 | -26,085,605 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,085,605.
Example:
1 x 26,085,605 = 26,085,605
and
-1 x -26,085,605 = 26,085,605
Notice both answers equal 26,085,605
With that explanation out of the way, let's continue. Next, we take the number 26,085,605 and divide it by 2:
26,085,605 ÷ 2 = 13,042,802.5
If the quotient is a whole number, then 2 and 13,042,802.5 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 | 26,085,605 | |
| -1 | -26,085,605 |
Now, we try dividing 26,085,605 by 3:
26,085,605 ÷ 3 = 8,695,201.6667
If the quotient is a whole number, then 3 and 8,695,201.6667 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 | 26,085,605 | |
| -1 | -26,085,605 |
Let's try dividing by 4:
26,085,605 ÷ 4 = 6,521,401.25
If the quotient is a whole number, then 4 and 6,521,401.25 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 | 26,085,605 | |
| -1 | 26,085,605 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 65 | 91 | 455 | 57,331 | 286,655 | 401,317 | 745,303 | 2,006,585 | 3,726,515 | 5,217,121 | 26,085,605 |
| -1 | -5 | -7 | -13 | -35 | -65 | -91 | -455 | -57,331 | -286,655 | -401,317 | -745,303 | -2,006,585 | -3,726,515 | -5,217,121 | -26,085,605 |
