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 511,373,605, 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 | 511,373,605 | |
| -1 | -511,373,605 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 511,373,605.
Example:
1 x 511,373,605 = 511,373,605
and
-1 x -511,373,605 = 511,373,605
Notice both answers equal 511,373,605
With that explanation out of the way, let's continue. Next, we take the number 511,373,605 and divide it by 2:
511,373,605 ÷ 2 = 255,686,802.5
If the quotient is a whole number, then 2 and 255,686,802.5 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 | 511,373,605 | |
| -1 | -511,373,605 |
Now, we try dividing 511,373,605 by 3:
511,373,605 ÷ 3 = 170,457,868.3333
If the quotient is a whole number, then 3 and 170,457,868.3333 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 | 511,373,605 | |
| -1 | -511,373,605 |
Let's try dividing by 4:
511,373,605 ÷ 4 = 127,843,401.25
If the quotient is a whole number, then 4 and 127,843,401.25 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 | 511,373,605 | |
| -1 | 511,373,605 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 101 | 115 | 505 | 2,323 | 11,615 | 44,027 | 220,135 | 1,012,621 | 4,446,727 | 5,063,105 | 22,233,635 | 102,274,721 | 511,373,605 |
| -1 | -5 | -23 | -101 | -115 | -505 | -2,323 | -11,615 | -44,027 | -220,135 | -1,012,621 | -4,446,727 | -5,063,105 | -22,233,635 | -102,274,721 | -511,373,605 |
