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 511,504,337, 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 | 511,504,337 | |
| -1 | -511,504,337 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 511,504,337.
Example:
1 x 511,504,337 = 511,504,337
and
-1 x -511,504,337 = 511,504,337
Notice both answers equal 511,504,337
With that explanation out of the way, let's continue. Next, we take the number 511,504,337 and divide it by 2:
511,504,337 ÷ 2 = 255,752,168.5
If the quotient is a whole number, then 2 and 255,752,168.5 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 | 511,504,337 | |
| -1 | -511,504,337 |
Now, we try dividing 511,504,337 by 3:
511,504,337 ÷ 3 = 170,501,445.6667
If the quotient is a whole number, then 3 and 170,501,445.6667 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 | 511,504,337 | |
| -1 | -511,504,337 |
Let's try dividing by 4:
511,504,337 ÷ 4 = 127,876,084.25
If the quotient is a whole number, then 4 and 127,876,084.25 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 | 511,504,337 | |
| -1 | 511,504,337 |
If you did it right, you will end up with this table:
| 1 | 23 | 47 | 61 | 1,081 | 1,403 | 2,867 | 7,757 | 65,941 | 178,411 | 364,579 | 473,177 | 8,385,317 | 10,883,071 | 22,239,319 | 511,504,337 |
| -1 | -23 | -47 | -61 | -1,081 | -1,403 | -2,867 | -7,757 | -65,941 | -178,411 | -364,579 | -473,177 | -8,385,317 | -10,883,071 | -22,239,319 | -511,504,337 |
