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 516,615,425, 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 | 516,615,425 | |
| -1 | -516,615,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 516,615,425.
Example:
1 x 516,615,425 = 516,615,425
and
-1 x -516,615,425 = 516,615,425
Notice both answers equal 516,615,425
With that explanation out of the way, let's continue. Next, we take the number 516,615,425 and divide it by 2:
516,615,425 ÷ 2 = 258,307,712.5
If the quotient is a whole number, then 2 and 258,307,712.5 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 | 516,615,425 | |
| -1 | -516,615,425 |
Now, we try dividing 516,615,425 by 3:
516,615,425 ÷ 3 = 172,205,141.6667
If the quotient is a whole number, then 3 and 172,205,141.6667 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 | 516,615,425 | |
| -1 | -516,615,425 |
Let's try dividing by 4:
516,615,425 ÷ 4 = 129,153,856.25
If the quotient is a whole number, then 4 and 129,153,856.25 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 | 516,615,425 | |
| -1 | 516,615,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 29 | 145 | 725 | 712,573 | 3,562,865 | 17,814,325 | 20,664,617 | 103,323,085 | 516,615,425 |
| -1 | -5 | -25 | -29 | -145 | -725 | -712,573 | -3,562,865 | -17,814,325 | -20,664,617 | -103,323,085 | -516,615,425 |
