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 25,623,125, 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 | 25,623,125 | |
| -1 | -25,623,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,623,125.
Example:
1 x 25,623,125 = 25,623,125
and
-1 x -25,623,125 = 25,623,125
Notice both answers equal 25,623,125
With that explanation out of the way, let's continue. Next, we take the number 25,623,125 and divide it by 2:
25,623,125 ÷ 2 = 12,811,562.5
If the quotient is a whole number, then 2 and 12,811,562.5 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 | 25,623,125 | |
| -1 | -25,623,125 |
Now, we try dividing 25,623,125 by 3:
25,623,125 ÷ 3 = 8,541,041.6667
If the quotient is a whole number, then 3 and 8,541,041.6667 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 | 25,623,125 | |
| -1 | -25,623,125 |
Let's try dividing by 4:
25,623,125 ÷ 4 = 6,405,781.25
If the quotient is a whole number, then 4 and 6,405,781.25 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 | 25,623,125 | |
| -1 | 25,623,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 125 | 275 | 625 | 1,375 | 3,727 | 6,875 | 18,635 | 40,997 | 93,175 | 204,985 | 465,875 | 1,024,925 | 2,329,375 | 5,124,625 | 25,623,125 |
| -1 | -5 | -11 | -25 | -55 | -125 | -275 | -625 | -1,375 | -3,727 | -6,875 | -18,635 | -40,997 | -93,175 | -204,985 | -465,875 | -1,024,925 | -2,329,375 | -5,124,625 | -25,623,125 |
