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 232,032,115, 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 | 232,032,115 | |
| -1 | -232,032,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 232,032,115.
Example:
1 x 232,032,115 = 232,032,115
and
-1 x -232,032,115 = 232,032,115
Notice both answers equal 232,032,115
With that explanation out of the way, let's continue. Next, we take the number 232,032,115 and divide it by 2:
232,032,115 ÷ 2 = 116,016,057.5
If the quotient is a whole number, then 2 and 116,016,057.5 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 | 232,032,115 | |
| -1 | -232,032,115 |
Now, we try dividing 232,032,115 by 3:
232,032,115 ÷ 3 = 77,344,038.3333
If the quotient is a whole number, then 3 and 77,344,038.3333 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 | 232,032,115 | |
| -1 | -232,032,115 |
Let's try dividing by 4:
232,032,115 ÷ 4 = 58,008,028.75
If the quotient is a whole number, then 4 and 58,008,028.75 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 | 232,032,115 | |
| -1 | 232,032,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 109 | 545 | 763 | 3,815 | 60,821 | 304,105 | 425,747 | 2,128,735 | 6,629,489 | 33,147,445 | 46,406,423 | 232,032,115 |
| -1 | -5 | -7 | -35 | -109 | -545 | -763 | -3,815 | -60,821 | -304,105 | -425,747 | -2,128,735 | -6,629,489 | -33,147,445 | -46,406,423 | -232,032,115 |
