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 306,371,375, 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 | 306,371,375 | |
| -1 | -306,371,375 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 306,371,375.
Example:
1 x 306,371,375 = 306,371,375
and
-1 x -306,371,375 = 306,371,375
Notice both answers equal 306,371,375
With that explanation out of the way, let's continue. Next, we take the number 306,371,375 and divide it by 2:
306,371,375 ÷ 2 = 153,185,687.5
If the quotient is a whole number, then 2 and 153,185,687.5 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 | 306,371,375 | |
| -1 | -306,371,375 |
Now, we try dividing 306,371,375 by 3:
306,371,375 ÷ 3 = 102,123,791.6667
If the quotient is a whole number, then 3 and 102,123,791.6667 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 | 306,371,375 | |
| -1 | -306,371,375 |
Let's try dividing by 4:
306,371,375 ÷ 4 = 76,592,843.75
If the quotient is a whole number, then 4 and 76,592,843.75 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 | 306,371,375 | |
| -1 | 306,371,375 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 89 | 125 | 445 | 2,225 | 11,125 | 27,539 | 137,695 | 688,475 | 2,450,971 | 3,442,375 | 12,254,855 | 61,274,275 | 306,371,375 |
| -1 | -5 | -25 | -89 | -125 | -445 | -2,225 | -11,125 | -27,539 | -137,695 | -688,475 | -2,450,971 | -3,442,375 | -12,254,855 | -61,274,275 | -306,371,375 |
