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 521,320,129, 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 | 521,320,129 | |
| -1 | -521,320,129 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 521,320,129.
Example:
1 x 521,320,129 = 521,320,129
and
-1 x -521,320,129 = 521,320,129
Notice both answers equal 521,320,129
With that explanation out of the way, let's continue. Next, we take the number 521,320,129 and divide it by 2:
521,320,129 ÷ 2 = 260,660,064.5
If the quotient is a whole number, then 2 and 260,660,064.5 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 | 521,320,129 | |
| -1 | -521,320,129 |
Now, we try dividing 521,320,129 by 3:
521,320,129 ÷ 3 = 173,773,376.3333
If the quotient is a whole number, then 3 and 173,773,376.3333 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 | 521,320,129 | |
| -1 | -521,320,129 |
Let's try dividing by 4:
521,320,129 ÷ 4 = 130,330,032.25
If the quotient is a whole number, then 4 and 130,330,032.25 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 | 521,320,129 | |
| -1 | 521,320,129 |
If you did it right, you will end up with this table:
| 1 | 11 | 163 | 479 | 607 | 1,793 | 5,269 | 6,677 | 78,077 | 98,941 | 290,753 | 858,847 | 1,088,351 | 3,198,283 | 47,392,739 | 521,320,129 |
| -1 | -11 | -163 | -479 | -607 | -1,793 | -5,269 | -6,677 | -78,077 | -98,941 | -290,753 | -858,847 | -1,088,351 | -3,198,283 | -47,392,739 | -521,320,129 |
