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 26,036,605, 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 | 26,036,605 | |
| -1 | -26,036,605 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,036,605.
Example:
1 x 26,036,605 = 26,036,605
and
-1 x -26,036,605 = 26,036,605
Notice both answers equal 26,036,605
With that explanation out of the way, let's continue. Next, we take the number 26,036,605 and divide it by 2:
26,036,605 ÷ 2 = 13,018,302.5
If the quotient is a whole number, then 2 and 13,018,302.5 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 | 26,036,605 | |
| -1 | -26,036,605 |
Now, we try dividing 26,036,605 by 3:
26,036,605 ÷ 3 = 8,678,868.3333
If the quotient is a whole number, then 3 and 8,678,868.3333 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 | 26,036,605 | |
| -1 | -26,036,605 |
Let's try dividing by 4:
26,036,605 ÷ 4 = 6,509,151.25
If the quotient is a whole number, then 4 and 6,509,151.25 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 | 26,036,605 | |
| -1 | 26,036,605 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 35 | 85 | 119 | 595 | 43,759 | 218,795 | 306,313 | 743,903 | 1,531,565 | 3,719,515 | 5,207,321 | 26,036,605 |
| -1 | -5 | -7 | -17 | -35 | -85 | -119 | -595 | -43,759 | -218,795 | -306,313 | -743,903 | -1,531,565 | -3,719,515 | -5,207,321 | -26,036,605 |
