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 516,925, 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 | 516,925 | |
| -1 | -516,925 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 516,925.
Example:
1 x 516,925 = 516,925
and
-1 x -516,925 = 516,925
Notice both answers equal 516,925
With that explanation out of the way, let's continue. Next, we take the number 516,925 and divide it by 2:
516,925 ÷ 2 = 258,462.5
If the quotient is a whole number, then 2 and 258,462.5 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 | 516,925 | |
| -1 | -516,925 |
Now, we try dividing 516,925 by 3:
516,925 ÷ 3 = 172,308.3333
If the quotient is a whole number, then 3 and 172,308.3333 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 | 516,925 | |
| -1 | -516,925 |
Let's try dividing by 4:
516,925 ÷ 4 = 129,231.25
If the quotient is a whole number, then 4 and 129,231.25 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 | 516,925 | |
| -1 | 516,925 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 25 | 29 | 31 | 115 | 145 | 155 | 575 | 667 | 713 | 725 | 775 | 899 | 3,335 | 3,565 | 4,495 | 16,675 | 17,825 | 20,677 | 22,475 | 103,385 | 516,925 |
| -1 | -5 | -23 | -25 | -29 | -31 | -115 | -145 | -155 | -575 | -667 | -713 | -725 | -775 | -899 | -3,335 | -3,565 | -4,495 | -16,675 | -17,825 | -20,677 | -22,475 | -103,385 | -516,925 |
