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 30,632,309, 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 | 30,632,309 | |
| -1 | -30,632,309 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,632,309.
Example:
1 x 30,632,309 = 30,632,309
and
-1 x -30,632,309 = 30,632,309
Notice both answers equal 30,632,309
With that explanation out of the way, let's continue. Next, we take the number 30,632,309 and divide it by 2:
30,632,309 ÷ 2 = 15,316,154.5
If the quotient is a whole number, then 2 and 15,316,154.5 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 | 30,632,309 | |
| -1 | -30,632,309 |
Now, we try dividing 30,632,309 by 3:
30,632,309 ÷ 3 = 10,210,769.6667
If the quotient is a whole number, then 3 and 10,210,769.6667 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 | 30,632,309 | |
| -1 | -30,632,309 |
Let's try dividing by 4:
30,632,309 ÷ 4 = 7,658,077.25
If the quotient is a whole number, then 4 and 7,658,077.25 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 | 30,632,309 | |
| -1 | 30,632,309 |
If you did it right, you will end up with this table:
| 1 | 31 | 61 | 97 | 167 | 1,891 | 3,007 | 5,177 | 5,917 | 10,187 | 16,199 | 183,427 | 315,797 | 502,169 | 988,139 | 30,632,309 |
| -1 | -31 | -61 | -97 | -167 | -1,891 | -3,007 | -5,177 | -5,917 | -10,187 | -16,199 | -183,427 | -315,797 | -502,169 | -988,139 | -30,632,309 |
