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 25,530,875, 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 | 25,530,875 | |
| -1 | -25,530,875 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,530,875.
Example:
1 x 25,530,875 = 25,530,875
and
-1 x -25,530,875 = 25,530,875
Notice both answers equal 25,530,875
With that explanation out of the way, let's continue. Next, we take the number 25,530,875 and divide it by 2:
25,530,875 ÷ 2 = 12,765,437.5
If the quotient is a whole number, then 2 and 12,765,437.5 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 | 25,530,875 | |
| -1 | -25,530,875 |
Now, we try dividing 25,530,875 by 3:
25,530,875 ÷ 3 = 8,510,291.6667
If the quotient is a whole number, then 3 and 8,510,291.6667 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 | 25,530,875 | |
| -1 | -25,530,875 |
Let's try dividing by 4:
25,530,875 ÷ 4 = 6,382,718.75
If the quotient is a whole number, then 4 and 6,382,718.75 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 | 25,530,875 | |
| -1 | 25,530,875 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 29 | 125 | 145 | 725 | 3,625 | 7,043 | 35,215 | 176,075 | 204,247 | 880,375 | 1,021,235 | 5,106,175 | 25,530,875 |
| -1 | -5 | -25 | -29 | -125 | -145 | -725 | -3,625 | -7,043 | -35,215 | -176,075 | -204,247 | -880,375 | -1,021,235 | -5,106,175 | -25,530,875 |
