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 2,555,231, 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 | 2,555,231 | |
| -1 | -2,555,231 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,555,231.
Example:
1 x 2,555,231 = 2,555,231
and
-1 x -2,555,231 = 2,555,231
Notice both answers equal 2,555,231
With that explanation out of the way, let's continue. Next, we take the number 2,555,231 and divide it by 2:
2,555,231 ÷ 2 = 1,277,615.5
If the quotient is a whole number, then 2 and 1,277,615.5 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 | 2,555,231 | |
| -1 | -2,555,231 |
Now, we try dividing 2,555,231 by 3:
2,555,231 ÷ 3 = 851,743.6667
If the quotient is a whole number, then 3 and 851,743.6667 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 | 2,555,231 | |
| -1 | -2,555,231 |
Let's try dividing by 4:
2,555,231 ÷ 4 = 638,807.75
If the quotient is a whole number, then 4 and 638,807.75 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 | 2,555,231 | |
| -1 | 2,555,231 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 59 | 161 | 269 | 413 | 1,357 | 1,883 | 6,187 | 9,499 | 15,871 | 43,309 | 111,097 | 365,033 | 2,555,231 |
| -1 | -7 | -23 | -59 | -161 | -269 | -413 | -1,357 | -1,883 | -6,187 | -9,499 | -15,871 | -43,309 | -111,097 | -365,033 | -2,555,231 |
