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 255,764,531, 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 | 255,764,531 | |
| -1 | -255,764,531 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 255,764,531.
Example:
1 x 255,764,531 = 255,764,531
and
-1 x -255,764,531 = 255,764,531
Notice both answers equal 255,764,531
With that explanation out of the way, let's continue. Next, we take the number 255,764,531 and divide it by 2:
255,764,531 ÷ 2 = 127,882,265.5
If the quotient is a whole number, then 2 and 127,882,265.5 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 | 255,764,531 | |
| -1 | -255,764,531 |
Now, we try dividing 255,764,531 by 3:
255,764,531 ÷ 3 = 85,254,843.6667
If the quotient is a whole number, then 3 and 85,254,843.6667 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 | 255,764,531 | |
| -1 | -255,764,531 |
Let's try dividing by 4:
255,764,531 ÷ 4 = 63,941,132.75
If the quotient is a whole number, then 4 and 63,941,132.75 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 | 255,764,531 | |
| -1 | 255,764,531 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 131 | 253 | 1,441 | 3,013 | 7,717 | 33,143 | 84,887 | 177,491 | 1,010,927 | 1,952,401 | 11,120,197 | 23,251,321 | 255,764,531 |
| -1 | -11 | -23 | -131 | -253 | -1,441 | -3,013 | -7,717 | -33,143 | -84,887 | -177,491 | -1,010,927 | -1,952,401 | -11,120,197 | -23,251,321 | -255,764,531 |
