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 516,404,125, 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 | 516,404,125 | |
| -1 | -516,404,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 516,404,125.
Example:
1 x 516,404,125 = 516,404,125
and
-1 x -516,404,125 = 516,404,125
Notice both answers equal 516,404,125
With that explanation out of the way, let's continue. Next, we take the number 516,404,125 and divide it by 2:
516,404,125 ÷ 2 = 258,202,062.5
If the quotient is a whole number, then 2 and 258,202,062.5 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 | 516,404,125 | |
| -1 | -516,404,125 |
Now, we try dividing 516,404,125 by 3:
516,404,125 ÷ 3 = 172,134,708.3333
If the quotient is a whole number, then 3 and 172,134,708.3333 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 | 516,404,125 | |
| -1 | -516,404,125 |
Let's try dividing by 4:
516,404,125 ÷ 4 = 129,101,031.25
If the quotient is a whole number, then 4 and 129,101,031.25 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 | 516,404,125 | |
| -1 | 516,404,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 937 | 4,409 | 4,685 | 22,045 | 23,425 | 110,225 | 117,125 | 551,125 | 4,131,233 | 20,656,165 | 103,280,825 | 516,404,125 |
| -1 | -5 | -25 | -125 | -937 | -4,409 | -4,685 | -22,045 | -23,425 | -110,225 | -117,125 | -551,125 | -4,131,233 | -20,656,165 | -103,280,825 | -516,404,125 |
