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 306,212,753, 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 | 306,212,753 | |
| -1 | -306,212,753 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 306,212,753.
Example:
1 x 306,212,753 = 306,212,753
and
-1 x -306,212,753 = 306,212,753
Notice both answers equal 306,212,753
With that explanation out of the way, let's continue. Next, we take the number 306,212,753 and divide it by 2:
306,212,753 ÷ 2 = 153,106,376.5
If the quotient is a whole number, then 2 and 153,106,376.5 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 | 306,212,753 | |
| -1 | -306,212,753 |
Now, we try dividing 306,212,753 by 3:
306,212,753 ÷ 3 = 102,070,917.6667
If the quotient is a whole number, then 3 and 102,070,917.6667 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 | 306,212,753 | |
| -1 | -306,212,753 |
Let's try dividing by 4:
306,212,753 ÷ 4 = 76,553,188.25
If the quotient is a whole number, then 4 and 76,553,188.25 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 | 306,212,753 | |
| -1 | 306,212,753 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 719 | 5,033 | 5,531 | 7,909 | 38,717 | 55,363 | 60,841 | 425,887 | 3,976,789 | 27,837,523 | 43,744,679 | 306,212,753 |
| -1 | -7 | -11 | -77 | -719 | -5,033 | -5,531 | -7,909 | -38,717 | -55,363 | -60,841 | -425,887 | -3,976,789 | -27,837,523 | -43,744,679 | -306,212,753 |
