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 520,355,209, 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 | 520,355,209 | |
| -1 | -520,355,209 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 520,355,209.
Example:
1 x 520,355,209 = 520,355,209
and
-1 x -520,355,209 = 520,355,209
Notice both answers equal 520,355,209
With that explanation out of the way, let's continue. Next, we take the number 520,355,209 and divide it by 2:
520,355,209 ÷ 2 = 260,177,604.5
If the quotient is a whole number, then 2 and 260,177,604.5 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 | 520,355,209 | |
| -1 | -520,355,209 |
Now, we try dividing 520,355,209 by 3:
520,355,209 ÷ 3 = 173,451,736.3333
If the quotient is a whole number, then 3 and 173,451,736.3333 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 | 520,355,209 | |
| -1 | -520,355,209 |
Let's try dividing by 4:
520,355,209 ÷ 4 = 130,088,802.25
If the quotient is a whole number, then 4 and 130,088,802.25 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 | 520,355,209 | |
| -1 | 520,355,209 |
If you did it right, you will end up with this table:
| 1 | 11 | 109 | 197 | 1,199 | 2,167 | 2,203 | 21,473 | 24,233 | 236,203 | 240,127 | 433,991 | 2,641,397 | 4,773,901 | 47,305,019 | 520,355,209 |
| -1 | -11 | -109 | -197 | -1,199 | -2,167 | -2,203 | -21,473 | -24,233 | -236,203 | -240,127 | -433,991 | -2,641,397 | -4,773,901 | -47,305,019 | -520,355,209 |
