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 230,302,331, 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 | 230,302,331 | |
| -1 | -230,302,331 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 230,302,331.
Example:
1 x 230,302,331 = 230,302,331
and
-1 x -230,302,331 = 230,302,331
Notice both answers equal 230,302,331
With that explanation out of the way, let's continue. Next, we take the number 230,302,331 and divide it by 2:
230,302,331 ÷ 2 = 115,151,165.5
If the quotient is a whole number, then 2 and 115,151,165.5 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 | 230,302,331 | |
| -1 | -230,302,331 |
Now, we try dividing 230,302,331 by 3:
230,302,331 ÷ 3 = 76,767,443.6667
If the quotient is a whole number, then 3 and 76,767,443.6667 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 | 230,302,331 | |
| -1 | -230,302,331 |
Let's try dividing by 4:
230,302,331 ÷ 4 = 57,575,582.75
If the quotient is a whole number, then 4 and 57,575,582.75 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 | 230,302,331 | |
| -1 | 230,302,331 |
If you did it right, you will end up with this table:
| 1 | 7 | 53 | 151 | 371 | 1,057 | 4,111 | 8,003 | 28,777 | 56,021 | 217,883 | 620,761 | 1,525,181 | 4,345,327 | 32,900,333 | 230,302,331 |
| -1 | -7 | -53 | -151 | -371 | -1,057 | -4,111 | -8,003 | -28,777 | -56,021 | -217,883 | -620,761 | -1,525,181 | -4,345,327 | -32,900,333 | -230,302,331 |
