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 306,848,623, 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 | 306,848,623 | |
| -1 | -306,848,623 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 306,848,623.
Example:
1 x 306,848,623 = 306,848,623
and
-1 x -306,848,623 = 306,848,623
Notice both answers equal 306,848,623
With that explanation out of the way, let's continue. Next, we take the number 306,848,623 and divide it by 2:
306,848,623 ÷ 2 = 153,424,311.5
If the quotient is a whole number, then 2 and 153,424,311.5 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 | 306,848,623 | |
| -1 | -306,848,623 |
Now, we try dividing 306,848,623 by 3:
306,848,623 ÷ 3 = 102,282,874.3333
If the quotient is a whole number, then 3 and 102,282,874.3333 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 | 306,848,623 | |
| -1 | -306,848,623 |
Let's try dividing by 4:
306,848,623 ÷ 4 = 76,712,155.75
If the quotient is a whole number, then 4 and 76,712,155.75 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 | 306,848,623 | |
| -1 | 306,848,623 |
If you did it right, you will end up with this table:
| 1 | 17 | 29 | 493 | 641 | 971 | 10,897 | 16,507 | 18,589 | 28,159 | 316,013 | 478,703 | 622,411 | 10,580,987 | 18,049,919 | 306,848,623 |
| -1 | -17 | -29 | -493 | -641 | -971 | -10,897 | -16,507 | -18,589 | -28,159 | -316,013 | -478,703 | -622,411 | -10,580,987 | -18,049,919 | -306,848,623 |
