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 123,023,329, 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 | 123,023,329 | |
| -1 | -123,023,329 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 123,023,329.
Example:
1 x 123,023,329 = 123,023,329
and
-1 x -123,023,329 = 123,023,329
Notice both answers equal 123,023,329
With that explanation out of the way, let's continue. Next, we take the number 123,023,329 and divide it by 2:
123,023,329 ÷ 2 = 61,511,664.5
If the quotient is a whole number, then 2 and 61,511,664.5 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 | 123,023,329 | |
| -1 | -123,023,329 |
Now, we try dividing 123,023,329 by 3:
123,023,329 ÷ 3 = 41,007,776.3333
If the quotient is a whole number, then 3 and 41,007,776.3333 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 | 123,023,329 | |
| -1 | -123,023,329 |
Let's try dividing by 4:
123,023,329 ÷ 4 = 30,755,832.25
If the quotient is a whole number, then 4 and 30,755,832.25 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 | 123,023,329 | |
| -1 | 123,023,329 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 41 | 143 | 451 | 533 | 5,863 | 20,983 | 230,813 | 272,779 | 860,303 | 3,000,569 | 9,463,333 | 11,183,939 | 123,023,329 |
| -1 | -11 | -13 | -41 | -143 | -451 | -533 | -5,863 | -20,983 | -230,813 | -272,779 | -860,303 | -3,000,569 | -9,463,333 | -11,183,939 | -123,023,329 |
