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 25,524,875, 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 | 25,524,875 | |
| -1 | -25,524,875 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,524,875.
Example:
1 x 25,524,875 = 25,524,875
and
-1 x -25,524,875 = 25,524,875
Notice both answers equal 25,524,875
With that explanation out of the way, let's continue. Next, we take the number 25,524,875 and divide it by 2:
25,524,875 ÷ 2 = 12,762,437.5
If the quotient is a whole number, then 2 and 12,762,437.5 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 | 25,524,875 | |
| -1 | -25,524,875 |
Now, we try dividing 25,524,875 by 3:
25,524,875 ÷ 3 = 8,508,291.6667
If the quotient is a whole number, then 3 and 8,508,291.6667 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 | 25,524,875 | |
| -1 | -25,524,875 |
Let's try dividing by 4:
25,524,875 ÷ 4 = 6,381,218.75
If the quotient is a whole number, then 4 and 6,381,218.75 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 | 25,524,875 | |
| -1 | 25,524,875 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 59 | 125 | 295 | 1,475 | 3,461 | 7,375 | 17,305 | 86,525 | 204,199 | 432,625 | 1,020,995 | 5,104,975 | 25,524,875 |
| -1 | -5 | -25 | -59 | -125 | -295 | -1,475 | -3,461 | -7,375 | -17,305 | -86,525 | -204,199 | -432,625 | -1,020,995 | -5,104,975 | -25,524,875 |
