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 265,382,831, 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 | 265,382,831 | |
| -1 | -265,382,831 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 265,382,831.
Example:
1 x 265,382,831 = 265,382,831
and
-1 x -265,382,831 = 265,382,831
Notice both answers equal 265,382,831
With that explanation out of the way, let's continue. Next, we take the number 265,382,831 and divide it by 2:
265,382,831 ÷ 2 = 132,691,415.5
If the quotient is a whole number, then 2 and 132,691,415.5 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 | 265,382,831 | |
| -1 | -265,382,831 |
Now, we try dividing 265,382,831 by 3:
265,382,831 ÷ 3 = 88,460,943.6667
If the quotient is a whole number, then 3 and 88,460,943.6667 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 | 265,382,831 | |
| -1 | -265,382,831 |
Let's try dividing by 4:
265,382,831 ÷ 4 = 66,345,707.75
If the quotient is a whole number, then 4 and 66,345,707.75 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 | 265,382,831 | |
| -1 | 265,382,831 |
If you did it right, you will end up with this table:
| 1 | 7 | 139 | 311 | 877 | 973 | 2,177 | 6,139 | 43,229 | 121,903 | 272,747 | 302,603 | 853,321 | 1,909,229 | 37,911,833 | 265,382,831 |
| -1 | -7 | -139 | -311 | -877 | -973 | -2,177 | -6,139 | -43,229 | -121,903 | -272,747 | -302,603 | -853,321 | -1,909,229 | -37,911,833 | -265,382,831 |
