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 232,213,511, 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 | 232,213,511 | |
| -1 | -232,213,511 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 232,213,511.
Example:
1 x 232,213,511 = 232,213,511
and
-1 x -232,213,511 = 232,213,511
Notice both answers equal 232,213,511
With that explanation out of the way, let's continue. Next, we take the number 232,213,511 and divide it by 2:
232,213,511 ÷ 2 = 116,106,755.5
If the quotient is a whole number, then 2 and 116,106,755.5 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 | 232,213,511 | |
| -1 | -232,213,511 |
Now, we try dividing 232,213,511 by 3:
232,213,511 ÷ 3 = 77,404,503.6667
If the quotient is a whole number, then 3 and 77,404,503.6667 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 | 232,213,511 | |
| -1 | -232,213,511 |
Let's try dividing by 4:
232,213,511 ÷ 4 = 58,053,377.75
If the quotient is a whole number, then 4 and 58,053,377.75 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 | 232,213,511 | |
| -1 | 232,213,511 |
If you did it right, you will end up with this table:
| 1 | 47 | 53 | 73 | 1,277 | 2,491 | 3,431 | 3,869 | 60,019 | 67,681 | 93,221 | 181,843 | 3,181,007 | 4,381,387 | 4,940,713 | 232,213,511 |
| -1 | -47 | -53 | -73 | -1,277 | -2,491 | -3,431 | -3,869 | -60,019 | -67,681 | -93,221 | -181,843 | -3,181,007 | -4,381,387 | -4,940,713 | -232,213,511 |
