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 307,413,065, 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 | 307,413,065 | |
| -1 | -307,413,065 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 307,413,065.
Example:
1 x 307,413,065 = 307,413,065
and
-1 x -307,413,065 = 307,413,065
Notice both answers equal 307,413,065
With that explanation out of the way, let's continue. Next, we take the number 307,413,065 and divide it by 2:
307,413,065 ÷ 2 = 153,706,532.5
If the quotient is a whole number, then 2 and 153,706,532.5 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 | 307,413,065 | |
| -1 | -307,413,065 |
Now, we try dividing 307,413,065 by 3:
307,413,065 ÷ 3 = 102,471,021.6667
If the quotient is a whole number, then 3 and 102,471,021.6667 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 | 307,413,065 | |
| -1 | -307,413,065 |
Let's try dividing by 4:
307,413,065 ÷ 4 = 76,853,266.25
If the quotient is a whole number, then 4 and 76,853,266.25 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 | 307,413,065 | |
| -1 | 307,413,065 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 157 | 785 | 2,983 | 14,915 | 20,611 | 103,055 | 391,609 | 1,958,045 | 3,235,927 | 16,179,635 | 61,482,613 | 307,413,065 |
| -1 | -5 | -19 | -95 | -157 | -785 | -2,983 | -14,915 | -20,611 | -103,055 | -391,609 | -1,958,045 | -3,235,927 | -16,179,635 | -61,482,613 | -307,413,065 |
