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 307,407,683, 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 | 307,407,683 | |
| -1 | -307,407,683 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 307,407,683.
Example:
1 x 307,407,683 = 307,407,683
and
-1 x -307,407,683 = 307,407,683
Notice both answers equal 307,407,683
With that explanation out of the way, let's continue. Next, we take the number 307,407,683 and divide it by 2:
307,407,683 ÷ 2 = 153,703,841.5
If the quotient is a whole number, then 2 and 153,703,841.5 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 | 307,407,683 | |
| -1 | -307,407,683 |
Now, we try dividing 307,407,683 by 3:
307,407,683 ÷ 3 = 102,469,227.6667
If the quotient is a whole number, then 3 and 102,469,227.6667 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 | 307,407,683 | |
| -1 | -307,407,683 |
Let's try dividing by 4:
307,407,683 ÷ 4 = 76,851,920.75
If the quotient is a whole number, then 4 and 76,851,920.75 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 | 307,407,683 | |
| -1 | 307,407,683 |
If you did it right, you will end up with this table:
| 1 | 11 | 47 | 107 | 517 | 1,177 | 5,029 | 5,557 | 55,319 | 61,127 | 261,179 | 594,599 | 2,872,969 | 6,540,589 | 27,946,153 | 307,407,683 |
| -1 | -11 | -47 | -107 | -517 | -1,177 | -5,029 | -5,557 | -55,319 | -61,127 | -261,179 | -594,599 | -2,872,969 | -6,540,589 | -27,946,153 | -307,407,683 |
