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 25,614,355, 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 | 25,614,355 | |
| -1 | -25,614,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,614,355.
Example:
1 x 25,614,355 = 25,614,355
and
-1 x -25,614,355 = 25,614,355
Notice both answers equal 25,614,355
With that explanation out of the way, let's continue. Next, we take the number 25,614,355 and divide it by 2:
25,614,355 ÷ 2 = 12,807,177.5
If the quotient is a whole number, then 2 and 12,807,177.5 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 | 25,614,355 | |
| -1 | -25,614,355 |
Now, we try dividing 25,614,355 by 3:
25,614,355 ÷ 3 = 8,538,118.3333
If the quotient is a whole number, then 3 and 8,538,118.3333 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 | 25,614,355 | |
| -1 | -25,614,355 |
Let's try dividing by 4:
25,614,355 ÷ 4 = 6,403,588.75
If the quotient is a whole number, then 4 and 6,403,588.75 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 | 25,614,355 | |
| -1 | 25,614,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 313 | 1,259 | 1,565 | 4,069 | 6,295 | 16,367 | 20,345 | 81,835 | 394,067 | 1,970,335 | 5,122,871 | 25,614,355 |
| -1 | -5 | -13 | -65 | -313 | -1,259 | -1,565 | -4,069 | -6,295 | -16,367 | -20,345 | -81,835 | -394,067 | -1,970,335 | -5,122,871 | -25,614,355 |
