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 25,587,533, 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 | 25,587,533 | |
| -1 | -25,587,533 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,587,533.
Example:
1 x 25,587,533 = 25,587,533
and
-1 x -25,587,533 = 25,587,533
Notice both answers equal 25,587,533
With that explanation out of the way, let's continue. Next, we take the number 25,587,533 and divide it by 2:
25,587,533 ÷ 2 = 12,793,766.5
If the quotient is a whole number, then 2 and 12,793,766.5 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 | 25,587,533 | |
| -1 | -25,587,533 |
Now, we try dividing 25,587,533 by 3:
25,587,533 ÷ 3 = 8,529,177.6667
If the quotient is a whole number, then 3 and 8,529,177.6667 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 | 25,587,533 | |
| -1 | -25,587,533 |
Let's try dividing by 4:
25,587,533 ÷ 4 = 6,396,883.25
If the quotient is a whole number, then 4 and 6,396,883.25 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 | 25,587,533 | |
| -1 | 25,587,533 |
If you did it right, you will end up with this table:
| 1 | 17 | 59 | 97 | 263 | 1,003 | 1,649 | 4,471 | 5,723 | 15,517 | 25,511 | 97,291 | 263,789 | 433,687 | 1,505,149 | 25,587,533 |
| -1 | -17 | -59 | -97 | -263 | -1,003 | -1,649 | -4,471 | -5,723 | -15,517 | -25,511 | -97,291 | -263,789 | -433,687 | -1,505,149 | -25,587,533 |
