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 307,334,551, 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 | 307,334,551 | |
| -1 | -307,334,551 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 307,334,551.
Example:
1 x 307,334,551 = 307,334,551
and
-1 x -307,334,551 = 307,334,551
Notice both answers equal 307,334,551
With that explanation out of the way, let's continue. Next, we take the number 307,334,551 and divide it by 2:
307,334,551 ÷ 2 = 153,667,275.5
If the quotient is a whole number, then 2 and 153,667,275.5 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 | 307,334,551 | |
| -1 | -307,334,551 |
Now, we try dividing 307,334,551 by 3:
307,334,551 ÷ 3 = 102,444,850.3333
If the quotient is a whole number, then 3 and 102,444,850.3333 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 | 307,334,551 | |
| -1 | -307,334,551 |
Let's try dividing by 4:
307,334,551 ÷ 4 = 76,833,637.75
If the quotient is a whole number, then 4 and 76,833,637.75 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 | 307,334,551 | |
| -1 | 307,334,551 |
If you did it right, you will end up with this table:
| 1 | 17 | 47 | 193 | 799 | 1,993 | 3,281 | 9,071 | 33,881 | 93,671 | 154,207 | 384,649 | 1,592,407 | 6,539,033 | 18,078,503 | 307,334,551 |
| -1 | -17 | -47 | -193 | -799 | -1,993 | -3,281 | -9,071 | -33,881 | -93,671 | -154,207 | -384,649 | -1,592,407 | -6,539,033 | -18,078,503 | -307,334,551 |
