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 303,807,023, 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 | 303,807,023 | |
| -1 | -303,807,023 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 303,807,023.
Example:
1 x 303,807,023 = 303,807,023
and
-1 x -303,807,023 = 303,807,023
Notice both answers equal 303,807,023
With that explanation out of the way, let's continue. Next, we take the number 303,807,023 and divide it by 2:
303,807,023 ÷ 2 = 151,903,511.5
If the quotient is a whole number, then 2 and 151,903,511.5 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 | 303,807,023 | |
| -1 | -303,807,023 |
Now, we try dividing 303,807,023 by 3:
303,807,023 ÷ 3 = 101,269,007.6667
If the quotient is a whole number, then 3 and 101,269,007.6667 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 | 303,807,023 | |
| -1 | -303,807,023 |
Let's try dividing by 4:
303,807,023 ÷ 4 = 75,951,755.75
If the quotient is a whole number, then 4 and 75,951,755.75 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 | 303,807,023 | |
| -1 | 303,807,023 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 61 | 299 | 793 | 1,403 | 16,657 | 18,239 | 216,541 | 383,111 | 1,016,077 | 4,980,443 | 13,209,001 | 23,369,771 | 303,807,023 |
| -1 | -13 | -23 | -61 | -299 | -793 | -1,403 | -16,657 | -18,239 | -216,541 | -383,111 | -1,016,077 | -4,980,443 | -13,209,001 | -23,369,771 | -303,807,023 |
