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 25,853,875, 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 | 25,853,875 | |
| -1 | -25,853,875 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,853,875.
Example:
1 x 25,853,875 = 25,853,875
and
-1 x -25,853,875 = 25,853,875
Notice both answers equal 25,853,875
With that explanation out of the way, let's continue. Next, we take the number 25,853,875 and divide it by 2:
25,853,875 ÷ 2 = 12,926,937.5
If the quotient is a whole number, then 2 and 12,926,937.5 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 | 25,853,875 | |
| -1 | -25,853,875 |
Now, we try dividing 25,853,875 by 3:
25,853,875 ÷ 3 = 8,617,958.3333
If the quotient is a whole number, then 3 and 8,617,958.3333 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 | 25,853,875 | |
| -1 | -25,853,875 |
Let's try dividing by 4:
25,853,875 ÷ 4 = 6,463,468.75
If the quotient is a whole number, then 4 and 6,463,468.75 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 | 25,853,875 | |
| -1 | 25,853,875 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 107 | 125 | 535 | 1,933 | 2,675 | 9,665 | 13,375 | 48,325 | 206,831 | 241,625 | 1,034,155 | 5,170,775 | 25,853,875 |
| -1 | -5 | -25 | -107 | -125 | -535 | -1,933 | -2,675 | -9,665 | -13,375 | -48,325 | -206,831 | -241,625 | -1,034,155 | -5,170,775 | -25,853,875 |
