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 25,335,875, 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 | 25,335,875 | |
| -1 | -25,335,875 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,335,875.
Example:
1 x 25,335,875 = 25,335,875
and
-1 x -25,335,875 = 25,335,875
Notice both answers equal 25,335,875
With that explanation out of the way, let's continue. Next, we take the number 25,335,875 and divide it by 2:
25,335,875 ÷ 2 = 12,667,937.5
If the quotient is a whole number, then 2 and 12,667,937.5 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 | 25,335,875 | |
| -1 | -25,335,875 |
Now, we try dividing 25,335,875 by 3:
25,335,875 ÷ 3 = 8,445,291.6667
If the quotient is a whole number, then 3 and 8,445,291.6667 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 | 25,335,875 | |
| -1 | -25,335,875 |
Let's try dividing by 4:
25,335,875 ÷ 4 = 6,333,968.75
If the quotient is a whole number, then 4 and 6,333,968.75 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 | 25,335,875 | |
| -1 | 25,335,875 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 157 | 785 | 1,291 | 3,925 | 6,455 | 19,625 | 32,275 | 161,375 | 202,687 | 1,013,435 | 5,067,175 | 25,335,875 |
| -1 | -5 | -25 | -125 | -157 | -785 | -1,291 | -3,925 | -6,455 | -19,625 | -32,275 | -161,375 | -202,687 | -1,013,435 | -5,067,175 | -25,335,875 |
