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 25,652,459, 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 | 25,652,459 | |
| -1 | -25,652,459 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,652,459.
Example:
1 x 25,652,459 = 25,652,459
and
-1 x -25,652,459 = 25,652,459
Notice both answers equal 25,652,459
With that explanation out of the way, let's continue. Next, we take the number 25,652,459 and divide it by 2:
25,652,459 ÷ 2 = 12,826,229.5
If the quotient is a whole number, then 2 and 12,826,229.5 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 | 25,652,459 | |
| -1 | -25,652,459 |
Now, we try dividing 25,652,459 by 3:
25,652,459 ÷ 3 = 8,550,819.6667
If the quotient is a whole number, then 3 and 8,550,819.6667 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 | 25,652,459 | |
| -1 | -25,652,459 |
Let's try dividing by 4:
25,652,459 ÷ 4 = 6,413,114.75
If the quotient is a whole number, then 4 and 6,413,114.75 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 | 25,652,459 | |
| -1 | 25,652,459 |
If you did it right, you will end up with this table:
| 1 | 7 | 47 | 103 | 329 | 721 | 757 | 4,841 | 5,299 | 33,887 | 35,579 | 77,971 | 249,053 | 545,797 | 3,664,637 | 25,652,459 |
| -1 | -7 | -47 | -103 | -329 | -721 | -757 | -4,841 | -5,299 | -33,887 | -35,579 | -77,971 | -249,053 | -545,797 | -3,664,637 | -25,652,459 |
