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 516,425, 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 | 516,425 | |
| -1 | -516,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 516,425.
Example:
1 x 516,425 = 516,425
and
-1 x -516,425 = 516,425
Notice both answers equal 516,425
With that explanation out of the way, let's continue. Next, we take the number 516,425 and divide it by 2:
516,425 ÷ 2 = 258,212.5
If the quotient is a whole number, then 2 and 258,212.5 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 | 516,425 | |
| -1 | -516,425 |
Now, we try dividing 516,425 by 3:
516,425 ÷ 3 = 172,141.6667
If the quotient is a whole number, then 3 and 172,141.6667 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 | 516,425 | |
| -1 | -516,425 |
Let's try dividing by 4:
516,425 ÷ 4 = 129,106.25
If the quotient is a whole number, then 4 and 129,106.25 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 | 516,425 | |
| -1 | 516,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 25 | 35 | 65 | 91 | 175 | 227 | 325 | 455 | 1,135 | 1,589 | 2,275 | 2,951 | 5,675 | 7,945 | 14,755 | 20,657 | 39,725 | 73,775 | 103,285 | 516,425 |
| -1 | -5 | -7 | -13 | -25 | -35 | -65 | -91 | -175 | -227 | -325 | -455 | -1,135 | -1,589 | -2,275 | -2,951 | -5,675 | -7,945 | -14,755 | -20,657 | -39,725 | -73,775 | -103,285 | -516,425 |
