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 25,307,335, 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 | 25,307,335 | |
| -1 | -25,307,335 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,307,335.
Example:
1 x 25,307,335 = 25,307,335
and
-1 x -25,307,335 = 25,307,335
Notice both answers equal 25,307,335
With that explanation out of the way, let's continue. Next, we take the number 25,307,335 and divide it by 2:
25,307,335 ÷ 2 = 12,653,667.5
If the quotient is a whole number, then 2 and 12,653,667.5 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 | 25,307,335 | |
| -1 | -25,307,335 |
Now, we try dividing 25,307,335 by 3:
25,307,335 ÷ 3 = 8,435,778.3333
If the quotient is a whole number, then 3 and 8,435,778.3333 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 | 25,307,335 | |
| -1 | -25,307,335 |
Let's try dividing by 4:
25,307,335 ÷ 4 = 6,326,833.75
If the quotient is a whole number, then 4 and 6,326,833.75 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 | 25,307,335 | |
| -1 | 25,307,335 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 271 | 983 | 1,355 | 4,915 | 5,149 | 18,677 | 25,745 | 93,385 | 266,393 | 1,331,965 | 5,061,467 | 25,307,335 |
| -1 | -5 | -19 | -95 | -271 | -983 | -1,355 | -4,915 | -5,149 | -18,677 | -25,745 | -93,385 | -266,393 | -1,331,965 | -5,061,467 | -25,307,335 |
