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 306,343,115, 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 | 306,343,115 | |
| -1 | -306,343,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 306,343,115.
Example:
1 x 306,343,115 = 306,343,115
and
-1 x -306,343,115 = 306,343,115
Notice both answers equal 306,343,115
With that explanation out of the way, let's continue. Next, we take the number 306,343,115 and divide it by 2:
306,343,115 ÷ 2 = 153,171,557.5
If the quotient is a whole number, then 2 and 153,171,557.5 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 | 306,343,115 | |
| -1 | -306,343,115 |
Now, we try dividing 306,343,115 by 3:
306,343,115 ÷ 3 = 102,114,371.6667
If the quotient is a whole number, then 3 and 102,114,371.6667 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 | 306,343,115 | |
| -1 | -306,343,115 |
Let's try dividing by 4:
306,343,115 ÷ 4 = 76,585,778.75
If the quotient is a whole number, then 4 and 76,585,778.75 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 | 306,343,115 | |
| -1 | 306,343,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 103 | 515 | 1,339 | 6,695 | 45,757 | 228,785 | 594,841 | 2,974,205 | 4,712,971 | 23,564,855 | 61,268,623 | 306,343,115 |
| -1 | -5 | -13 | -65 | -103 | -515 | -1,339 | -6,695 | -45,757 | -228,785 | -594,841 | -2,974,205 | -4,712,971 | -23,564,855 | -61,268,623 | -306,343,115 |
