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 25,957,337, 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 | 25,957,337 | |
| -1 | -25,957,337 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,957,337.
Example:
1 x 25,957,337 = 25,957,337
and
-1 x -25,957,337 = 25,957,337
Notice both answers equal 25,957,337
With that explanation out of the way, let's continue. Next, we take the number 25,957,337 and divide it by 2:
25,957,337 ÷ 2 = 12,978,668.5
If the quotient is a whole number, then 2 and 12,978,668.5 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 | 25,957,337 | |
| -1 | -25,957,337 |
Now, we try dividing 25,957,337 by 3:
25,957,337 ÷ 3 = 8,652,445.6667
If the quotient is a whole number, then 3 and 8,652,445.6667 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 | 25,957,337 | |
| -1 | -25,957,337 |
Let's try dividing by 4:
25,957,337 ÷ 4 = 6,489,334.25
If the quotient is a whole number, then 4 and 6,489,334.25 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 | 25,957,337 | |
| -1 | 25,957,337 |
If you did it right, you will end up with this table:
| 1 | 7 | 43 | 83 | 301 | 581 | 1,039 | 3,569 | 7,273 | 24,983 | 44,677 | 86,237 | 312,739 | 603,659 | 3,708,191 | 25,957,337 |
| -1 | -7 | -43 | -83 | -301 | -581 | -1,039 | -3,569 | -7,273 | -24,983 | -44,677 | -86,237 | -312,739 | -603,659 | -3,708,191 | -25,957,337 |
