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 25,632,343, 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 | 25,632,343 | |
| -1 | -25,632,343 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,632,343.
Example:
1 x 25,632,343 = 25,632,343
and
-1 x -25,632,343 = 25,632,343
Notice both answers equal 25,632,343
With that explanation out of the way, let's continue. Next, we take the number 25,632,343 and divide it by 2:
25,632,343 ÷ 2 = 12,816,171.5
If the quotient is a whole number, then 2 and 12,816,171.5 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 | 25,632,343 | |
| -1 | -25,632,343 |
Now, we try dividing 25,632,343 by 3:
25,632,343 ÷ 3 = 8,544,114.3333
If the quotient is a whole number, then 3 and 8,544,114.3333 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 | 25,632,343 | |
| -1 | -25,632,343 |
Let's try dividing by 4:
25,632,343 ÷ 4 = 6,408,085.75
If the quotient is a whole number, then 4 and 6,408,085.75 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 | 25,632,343 | |
| -1 | 25,632,343 |
If you did it right, you will end up with this table:
| 1 | 11 | 43 | 47 | 473 | 517 | 1,153 | 2,021 | 12,683 | 22,231 | 49,579 | 54,191 | 545,369 | 596,101 | 2,330,213 | 25,632,343 |
| -1 | -11 | -43 | -47 | -473 | -517 | -1,153 | -2,021 | -12,683 | -22,231 | -49,579 | -54,191 | -545,369 | -596,101 | -2,330,213 | -25,632,343 |
