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 230,603,023, 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 | 230,603,023 | |
| -1 | -230,603,023 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 230,603,023.
Example:
1 x 230,603,023 = 230,603,023
and
-1 x -230,603,023 = 230,603,023
Notice both answers equal 230,603,023
With that explanation out of the way, let's continue. Next, we take the number 230,603,023 and divide it by 2:
230,603,023 ÷ 2 = 115,301,511.5
If the quotient is a whole number, then 2 and 115,301,511.5 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 | 230,603,023 | |
| -1 | -230,603,023 |
Now, we try dividing 230,603,023 by 3:
230,603,023 ÷ 3 = 76,867,674.3333
If the quotient is a whole number, then 3 and 76,867,674.3333 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 | 230,603,023 | |
| -1 | -230,603,023 |
Let's try dividing by 4:
230,603,023 ÷ 4 = 57,650,755.75
If the quotient is a whole number, then 4 and 57,650,755.75 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 | 230,603,023 | |
| -1 | 230,603,023 |
If you did it right, you will end up with this table:
| 1 | 7 | 43 | 301 | 809 | 947 | 5,663 | 6,629 | 34,787 | 40,721 | 243,509 | 285,047 | 766,123 | 5,362,861 | 32,943,289 | 230,603,023 |
| -1 | -7 | -43 | -301 | -809 | -947 | -5,663 | -6,629 | -34,787 | -40,721 | -243,509 | -285,047 | -766,123 | -5,362,861 | -32,943,289 | -230,603,023 |
