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 520,025, 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 | 520,025 | |
| -1 | -520,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 520,025.
Example:
1 x 520,025 = 520,025
and
-1 x -520,025 = 520,025
Notice both answers equal 520,025
With that explanation out of the way, let's continue. Next, we take the number 520,025 and divide it by 2:
520,025 ÷ 2 = 260,012.5
If the quotient is a whole number, then 2 and 260,012.5 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 | 520,025 | |
| -1 | -520,025 |
Now, we try dividing 520,025 by 3:
520,025 ÷ 3 = 173,341.6667
If the quotient is a whole number, then 3 and 173,341.6667 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 | 520,025 | |
| -1 | -520,025 |
Let's try dividing by 4:
520,025 ÷ 4 = 130,006.25
If the quotient is a whole number, then 4 and 130,006.25 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 | 520,025 | |
| -1 | 520,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 31 | 55 | 61 | 155 | 275 | 305 | 341 | 671 | 775 | 1,525 | 1,705 | 1,891 | 3,355 | 8,525 | 9,455 | 16,775 | 20,801 | 47,275 | 104,005 | 520,025 |
| -1 | -5 | -11 | -25 | -31 | -55 | -61 | -155 | -275 | -305 | -341 | -671 | -775 | -1,525 | -1,705 | -1,891 | -3,355 | -8,525 | -9,455 | -16,775 | -20,801 | -47,275 | -104,005 | -520,025 |
