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 511,504,325, 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 | 511,504,325 | |
| -1 | -511,504,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 511,504,325.
Example:
1 x 511,504,325 = 511,504,325
and
-1 x -511,504,325 = 511,504,325
Notice both answers equal 511,504,325
With that explanation out of the way, let's continue. Next, we take the number 511,504,325 and divide it by 2:
511,504,325 ÷ 2 = 255,752,162.5
If the quotient is a whole number, then 2 and 255,752,162.5 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 | 511,504,325 | |
| -1 | -511,504,325 |
Now, we try dividing 511,504,325 by 3:
511,504,325 ÷ 3 = 170,501,441.6667
If the quotient is a whole number, then 3 and 170,501,441.6667 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 | 511,504,325 | |
| -1 | -511,504,325 |
Let's try dividing by 4:
511,504,325 ÷ 4 = 127,876,081.25
If the quotient is a whole number, then 4 and 127,876,081.25 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 | 511,504,325 | |
| -1 | 511,504,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 53 | 265 | 1,325 | 386,041 | 1,930,205 | 9,651,025 | 20,460,173 | 102,300,865 | 511,504,325 |
| -1 | -5 | -25 | -53 | -265 | -1,325 | -386,041 | -1,930,205 | -9,651,025 | -20,460,173 | -102,300,865 | -511,504,325 |
