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 232,202,311, 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 | 232,202,311 | |
| -1 | -232,202,311 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 232,202,311.
Example:
1 x 232,202,311 = 232,202,311
and
-1 x -232,202,311 = 232,202,311
Notice both answers equal 232,202,311
With that explanation out of the way, let's continue. Next, we take the number 232,202,311 and divide it by 2:
232,202,311 ÷ 2 = 116,101,155.5
If the quotient is a whole number, then 2 and 116,101,155.5 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 | 232,202,311 | |
| -1 | -232,202,311 |
Now, we try dividing 232,202,311 by 3:
232,202,311 ÷ 3 = 77,400,770.3333
If the quotient is a whole number, then 3 and 77,400,770.3333 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 | 232,202,311 | |
| -1 | -232,202,311 |
Let's try dividing by 4:
232,202,311 ÷ 4 = 58,050,577.75
If the quotient is a whole number, then 4 and 58,050,577.75 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 | 232,202,311 | |
| -1 | 232,202,311 |
If you did it right, you will end up with this table:
| 1 | 11 | 41 | 167 | 451 | 1,837 | 3,083 | 6,847 | 33,913 | 75,317 | 126,403 | 514,861 | 1,390,433 | 5,663,471 | 21,109,301 | 232,202,311 |
| -1 | -11 | -41 | -167 | -451 | -1,837 | -3,083 | -6,847 | -33,913 | -75,317 | -126,403 | -514,861 | -1,390,433 | -5,663,471 | -21,109,301 | -232,202,311 |
