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 230,240,309, 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 | 230,240,309 | |
| -1 | -230,240,309 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 230,240,309.
Example:
1 x 230,240,309 = 230,240,309
and
-1 x -230,240,309 = 230,240,309
Notice both answers equal 230,240,309
With that explanation out of the way, let's continue. Next, we take the number 230,240,309 and divide it by 2:
230,240,309 ÷ 2 = 115,120,154.5
If the quotient is a whole number, then 2 and 115,120,154.5 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 | 230,240,309 | |
| -1 | -230,240,309 |
Now, we try dividing 230,240,309 by 3:
230,240,309 ÷ 3 = 76,746,769.6667
If the quotient is a whole number, then 3 and 76,746,769.6667 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 | 230,240,309 | |
| -1 | -230,240,309 |
Let's try dividing by 4:
230,240,309 ÷ 4 = 57,560,077.25
If the quotient is a whole number, then 4 and 57,560,077.25 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 | 230,240,309 | |
| -1 | 230,240,309 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 29 | 247 | 377 | 551 | 7,163 | 32,143 | 417,859 | 610,717 | 932,147 | 7,939,321 | 12,117,911 | 17,710,793 | 230,240,309 |
| -1 | -13 | -19 | -29 | -247 | -377 | -551 | -7,163 | -32,143 | -417,859 | -610,717 | -932,147 | -7,939,321 | -12,117,911 | -17,710,793 | -230,240,309 |
