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 310,246,517, 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 | 310,246,517 | |
| -1 | -310,246,517 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 310,246,517.
Example:
1 x 310,246,517 = 310,246,517
and
-1 x -310,246,517 = 310,246,517
Notice both answers equal 310,246,517
With that explanation out of the way, let's continue. Next, we take the number 310,246,517 and divide it by 2:
310,246,517 ÷ 2 = 155,123,258.5
If the quotient is a whole number, then 2 and 155,123,258.5 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 | 310,246,517 | |
| -1 | -310,246,517 |
Now, we try dividing 310,246,517 by 3:
310,246,517 ÷ 3 = 103,415,505.6667
If the quotient is a whole number, then 3 and 103,415,505.6667 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 | 310,246,517 | |
| -1 | -310,246,517 |
Let's try dividing by 4:
310,246,517 ÷ 4 = 77,561,629.25
If the quotient is a whole number, then 4 and 77,561,629.25 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 | 310,246,517 | |
| -1 | 310,246,517 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 37 | 161 | 259 | 851 | 5,957 | 52,081 | 364,567 | 1,197,863 | 1,926,997 | 8,385,041 | 13,488,979 | 44,320,931 | 310,246,517 |
| -1 | -7 | -23 | -37 | -161 | -259 | -851 | -5,957 | -52,081 | -364,567 | -1,197,863 | -1,926,997 | -8,385,041 | -13,488,979 | -44,320,931 | -310,246,517 |
