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 123,023,303, 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 | 123,023,303 | |
| -1 | -123,023,303 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 123,023,303.
Example:
1 x 123,023,303 = 123,023,303
and
-1 x -123,023,303 = 123,023,303
Notice both answers equal 123,023,303
With that explanation out of the way, let's continue. Next, we take the number 123,023,303 and divide it by 2:
123,023,303 ÷ 2 = 61,511,651.5
If the quotient is a whole number, then 2 and 61,511,651.5 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 | 123,023,303 | |
| -1 | -123,023,303 |
Now, we try dividing 123,023,303 by 3:
123,023,303 ÷ 3 = 41,007,767.6667
If the quotient is a whole number, then 3 and 41,007,767.6667 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 | 123,023,303 | |
| -1 | -123,023,303 |
Let's try dividing by 4:
123,023,303 ÷ 4 = 30,755,825.75
If the quotient is a whole number, then 4 and 30,755,825.75 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 | 123,023,303 | |
| -1 | 123,023,303 |
If you did it right, you will end up with this table:
| 1 | 13 | 79 | 103 | 1,027 | 1,163 | 1,339 | 8,137 | 15,119 | 91,877 | 105,781 | 119,789 | 1,194,401 | 1,557,257 | 9,463,331 | 123,023,303 |
| -1 | -13 | -79 | -103 | -1,027 | -1,163 | -1,339 | -8,137 | -15,119 | -91,877 | -105,781 | -119,789 | -1,194,401 | -1,557,257 | -9,463,331 | -123,023,303 |
