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 307,334,555, 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 | 307,334,555 | |
| -1 | -307,334,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 307,334,555.
Example:
1 x 307,334,555 = 307,334,555
and
-1 x -307,334,555 = 307,334,555
Notice both answers equal 307,334,555
With that explanation out of the way, let's continue. Next, we take the number 307,334,555 and divide it by 2:
307,334,555 ÷ 2 = 153,667,277.5
If the quotient is a whole number, then 2 and 153,667,277.5 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 | 307,334,555 | |
| -1 | -307,334,555 |
Now, we try dividing 307,334,555 by 3:
307,334,555 ÷ 3 = 102,444,851.6667
If the quotient is a whole number, then 3 and 102,444,851.6667 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 | 307,334,555 | |
| -1 | -307,334,555 |
Let's try dividing by 4:
307,334,555 ÷ 4 = 76,833,638.75
If the quotient is a whole number, then 4 and 76,833,638.75 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 | 307,334,555 | |
| -1 | 307,334,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 121 | 605 | 1,331 | 6,655 | 46,181 | 230,905 | 507,991 | 2,539,955 | 5,587,901 | 27,939,505 | 61,466,911 | 307,334,555 |
| -1 | -5 | -11 | -55 | -121 | -605 | -1,331 | -6,655 | -46,181 | -230,905 | -507,991 | -2,539,955 | -5,587,901 | -27,939,505 | -61,466,911 | -307,334,555 |
