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 382,767,931, 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 | 382,767,931 | |
| -1 | -382,767,931 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 382,767,931.
Example:
1 x 382,767,931 = 382,767,931
and
-1 x -382,767,931 = 382,767,931
Notice both answers equal 382,767,931
With that explanation out of the way, let's continue. Next, we take the number 382,767,931 and divide it by 2:
382,767,931 ÷ 2 = 191,383,965.5
If the quotient is a whole number, then 2 and 191,383,965.5 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 | 382,767,931 | |
| -1 | -382,767,931 |
Now, we try dividing 382,767,931 by 3:
382,767,931 ÷ 3 = 127,589,310.3333
If the quotient is a whole number, then 3 and 127,589,310.3333 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 | 382,767,931 | |
| -1 | -382,767,931 |
Let's try dividing by 4:
382,767,931 ÷ 4 = 95,691,982.75
If the quotient is a whole number, then 4 and 95,691,982.75 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 | 382,767,931 | |
| -1 | 382,767,931 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 169 | 1,183 | 2,197 | 15,379 | 24,889 | 174,223 | 323,557 | 2,264,899 | 4,206,241 | 29,443,687 | 54,681,133 | 382,767,931 |
| -1 | -7 | -13 | -91 | -169 | -1,183 | -2,197 | -15,379 | -24,889 | -174,223 | -323,557 | -2,264,899 | -4,206,241 | -29,443,687 | -54,681,133 | -382,767,931 |
