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 25,534,315, 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 | 25,534,315 | |
| -1 | -25,534,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,534,315.
Example:
1 x 25,534,315 = 25,534,315
and
-1 x -25,534,315 = 25,534,315
Notice both answers equal 25,534,315
With that explanation out of the way, let's continue. Next, we take the number 25,534,315 and divide it by 2:
25,534,315 ÷ 2 = 12,767,157.5
If the quotient is a whole number, then 2 and 12,767,157.5 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 | 25,534,315 | |
| -1 | -25,534,315 |
Now, we try dividing 25,534,315 by 3:
25,534,315 ÷ 3 = 8,511,438.3333
If the quotient is a whole number, then 3 and 8,511,438.3333 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 | 25,534,315 | |
| -1 | -25,534,315 |
Let's try dividing by 4:
25,534,315 ÷ 4 = 6,383,578.75
If the quotient is a whole number, then 4 and 6,383,578.75 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 | 25,534,315 | |
| -1 | 25,534,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 59 | 101 | 295 | 505 | 857 | 4,285 | 5,959 | 29,795 | 50,563 | 86,557 | 252,815 | 432,785 | 5,106,863 | 25,534,315 |
| -1 | -5 | -59 | -101 | -295 | -505 | -857 | -4,285 | -5,959 | -29,795 | -50,563 | -86,557 | -252,815 | -432,785 | -5,106,863 | -25,534,315 |
