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 307,505,555, 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 | 307,505,555 | |
| -1 | -307,505,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 307,505,555.
Example:
1 x 307,505,555 = 307,505,555
and
-1 x -307,505,555 = 307,505,555
Notice both answers equal 307,505,555
With that explanation out of the way, let's continue. Next, we take the number 307,505,555 and divide it by 2:
307,505,555 ÷ 2 = 153,752,777.5
If the quotient is a whole number, then 2 and 153,752,777.5 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 | 307,505,555 | |
| -1 | -307,505,555 |
Now, we try dividing 307,505,555 by 3:
307,505,555 ÷ 3 = 102,501,851.6667
If the quotient is a whole number, then 3 and 102,501,851.6667 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 | 307,505,555 | |
| -1 | -307,505,555 |
Let's try dividing by 4:
307,505,555 ÷ 4 = 76,876,388.75
If the quotient is a whole number, then 4 and 76,876,388.75 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 | 307,505,555 | |
| -1 | 307,505,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 1,097 | 5,485 | 7,679 | 8,009 | 38,395 | 40,045 | 56,063 | 280,315 | 8,785,873 | 43,929,365 | 61,501,111 | 307,505,555 |
| -1 | -5 | -7 | -35 | -1,097 | -5,485 | -7,679 | -8,009 | -38,395 | -40,045 | -56,063 | -280,315 | -8,785,873 | -43,929,365 | -61,501,111 | -307,505,555 |
