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 307,717,753, 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 | 307,717,753 | |
| -1 | -307,717,753 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 307,717,753.
Example:
1 x 307,717,753 = 307,717,753
and
-1 x -307,717,753 = 307,717,753
Notice both answers equal 307,717,753
With that explanation out of the way, let's continue. Next, we take the number 307,717,753 and divide it by 2:
307,717,753 ÷ 2 = 153,858,876.5
If the quotient is a whole number, then 2 and 153,858,876.5 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 | 307,717,753 | |
| -1 | -307,717,753 |
Now, we try dividing 307,717,753 by 3:
307,717,753 ÷ 3 = 102,572,584.3333
If the quotient is a whole number, then 3 and 102,572,584.3333 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 | 307,717,753 | |
| -1 | -307,717,753 |
Let's try dividing by 4:
307,717,753 ÷ 4 = 76,929,438.25
If the quotient is a whole number, then 4 and 76,929,438.25 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 | 307,717,753 | |
| -1 | 307,717,753 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 103 | 203 | 721 | 2,987 | 14,717 | 20,909 | 103,019 | 426,793 | 1,515,851 | 2,987,551 | 10,610,957 | 43,959,679 | 307,717,753 |
| -1 | -7 | -29 | -103 | -203 | -721 | -2,987 | -14,717 | -20,909 | -103,019 | -426,793 | -1,515,851 | -2,987,551 | -10,610,957 | -43,959,679 | -307,717,753 |
