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 520,404,335, 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 | 520,404,335 | |
| -1 | -520,404,335 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 520,404,335.
Example:
1 x 520,404,335 = 520,404,335
and
-1 x -520,404,335 = 520,404,335
Notice both answers equal 520,404,335
With that explanation out of the way, let's continue. Next, we take the number 520,404,335 and divide it by 2:
520,404,335 ÷ 2 = 260,202,167.5
If the quotient is a whole number, then 2 and 260,202,167.5 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 | 520,404,335 | |
| -1 | -520,404,335 |
Now, we try dividing 520,404,335 by 3:
520,404,335 ÷ 3 = 173,468,111.6667
If the quotient is a whole number, then 3 and 173,468,111.6667 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 | 520,404,335 | |
| -1 | -520,404,335 |
Let's try dividing by 4:
520,404,335 ÷ 4 = 130,101,083.75
If the quotient is a whole number, then 4 and 130,101,083.75 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 | 520,404,335 | |
| -1 | 520,404,335 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 233 | 1,165 | 2,563 | 12,815 | 40,609 | 203,045 | 446,699 | 2,233,495 | 9,461,897 | 47,309,485 | 104,080,867 | 520,404,335 |
| -1 | -5 | -11 | -55 | -233 | -1,165 | -2,563 | -12,815 | -40,609 | -203,045 | -446,699 | -2,233,495 | -9,461,897 | -47,309,485 | -104,080,867 | -520,404,335 |
