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 511,504,331, 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 | 511,504,331 | |
| -1 | -511,504,331 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 511,504,331.
Example:
1 x 511,504,331 = 511,504,331
and
-1 x -511,504,331 = 511,504,331
Notice both answers equal 511,504,331
With that explanation out of the way, let's continue. Next, we take the number 511,504,331 and divide it by 2:
511,504,331 ÷ 2 = 255,752,165.5
If the quotient is a whole number, then 2 and 255,752,165.5 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 | 511,504,331 | |
| -1 | -511,504,331 |
Now, we try dividing 511,504,331 by 3:
511,504,331 ÷ 3 = 170,501,443.6667
If the quotient is a whole number, then 3 and 170,501,443.6667 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 | 511,504,331 | |
| -1 | -511,504,331 |
Let's try dividing by 4:
511,504,331 ÷ 4 = 127,876,082.75
If the quotient is a whole number, then 4 and 127,876,082.75 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 | 511,504,331 | |
| -1 | 511,504,331 |
If you did it right, you will end up with this table:
| 1 | 13 | 67 | 113 | 871 | 1,469 | 5,197 | 7,571 | 67,561 | 98,423 | 348,199 | 587,261 | 4,526,587 | 7,634,393 | 39,346,487 | 511,504,331 |
| -1 | -13 | -67 | -113 | -871 | -1,469 | -5,197 | -7,571 | -67,561 | -98,423 | -348,199 | -587,261 | -4,526,587 | -7,634,393 | -39,346,487 | -511,504,331 |
