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 231,057,775, 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 | 231,057,775 | |
| -1 | -231,057,775 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 231,057,775.
Example:
1 x 231,057,775 = 231,057,775
and
-1 x -231,057,775 = 231,057,775
Notice both answers equal 231,057,775
With that explanation out of the way, let's continue. Next, we take the number 231,057,775 and divide it by 2:
231,057,775 ÷ 2 = 115,528,887.5
If the quotient is a whole number, then 2 and 115,528,887.5 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 | 231,057,775 | |
| -1 | -231,057,775 |
Now, we try dividing 231,057,775 by 3:
231,057,775 ÷ 3 = 77,019,258.3333
If the quotient is a whole number, then 3 and 77,019,258.3333 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 | 231,057,775 | |
| -1 | -231,057,775 |
Let's try dividing by 4:
231,057,775 ÷ 4 = 57,764,443.75
If the quotient is a whole number, then 4 and 57,764,443.75 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 | 231,057,775 | |
| -1 | 231,057,775 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 65 | 73 | 325 | 365 | 949 | 1,825 | 4,745 | 9,739 | 23,725 | 48,695 | 126,607 | 243,475 | 633,035 | 710,947 | 3,165,175 | 3,554,735 | 9,242,311 | 17,773,675 | 46,211,555 | 231,057,775 |
| -1 | -5 | -13 | -25 | -65 | -73 | -325 | -365 | -949 | -1,825 | -4,745 | -9,739 | -23,725 | -48,695 | -126,607 | -243,475 | -633,035 | -710,947 | -3,165,175 | -3,554,735 | -9,242,311 | -17,773,675 | -46,211,555 | -231,057,775 |
