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 26,002,625, 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 | 26,002,625 | |
| -1 | -26,002,625 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,002,625.
Example:
1 x 26,002,625 = 26,002,625
and
-1 x -26,002,625 = 26,002,625
Notice both answers equal 26,002,625
With that explanation out of the way, let's continue. Next, we take the number 26,002,625 and divide it by 2:
26,002,625 ÷ 2 = 13,001,312.5
If the quotient is a whole number, then 2 and 13,001,312.5 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 | 26,002,625 | |
| -1 | -26,002,625 |
Now, we try dividing 26,002,625 by 3:
26,002,625 ÷ 3 = 8,667,541.6667
If the quotient is a whole number, then 3 and 8,667,541.6667 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 | 26,002,625 | |
| -1 | -26,002,625 |
Let's try dividing by 4:
26,002,625 ÷ 4 = 6,500,656.25
If the quotient is a whole number, then 4 and 6,500,656.25 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 | 26,002,625 | |
| -1 | 26,002,625 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 125 | 275 | 1,375 | 18,911 | 94,555 | 208,021 | 472,775 | 1,040,105 | 2,363,875 | 5,200,525 | 26,002,625 |
| -1 | -5 | -11 | -25 | -55 | -125 | -275 | -1,375 | -18,911 | -94,555 | -208,021 | -472,775 | -1,040,105 | -2,363,875 | -5,200,525 | -26,002,625 |
