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 25,330,645, 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 | 25,330,645 | |
| -1 | -25,330,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,330,645.
Example:
1 x 25,330,645 = 25,330,645
and
-1 x -25,330,645 = 25,330,645
Notice both answers equal 25,330,645
With that explanation out of the way, let's continue. Next, we take the number 25,330,645 and divide it by 2:
25,330,645 ÷ 2 = 12,665,322.5
If the quotient is a whole number, then 2 and 12,665,322.5 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 | 25,330,645 | |
| -1 | -25,330,645 |
Now, we try dividing 25,330,645 by 3:
25,330,645 ÷ 3 = 8,443,548.3333
If the quotient is a whole number, then 3 and 8,443,548.3333 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 | 25,330,645 | |
| -1 | -25,330,645 |
Let's try dividing by 4:
25,330,645 ÷ 4 = 6,332,661.25
If the quotient is a whole number, then 4 and 6,332,661.25 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 | 25,330,645 | |
| -1 | 25,330,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 107 | 113 | 419 | 535 | 565 | 2,095 | 12,091 | 44,833 | 47,347 | 60,455 | 224,165 | 236,735 | 5,066,129 | 25,330,645 |
| -1 | -5 | -107 | -113 | -419 | -535 | -565 | -2,095 | -12,091 | -44,833 | -47,347 | -60,455 | -224,165 | -236,735 | -5,066,129 | -25,330,645 |
