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 520,135, 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 | 520,135 | |
| -1 | -520,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 520,135.
Example:
1 x 520,135 = 520,135
and
-1 x -520,135 = 520,135
Notice both answers equal 520,135
With that explanation out of the way, let's continue. Next, we take the number 520,135 and divide it by 2:
520,135 ÷ 2 = 260,067.5
If the quotient is a whole number, then 2 and 260,067.5 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 | 520,135 | |
| -1 | -520,135 |
Now, we try dividing 520,135 by 3:
520,135 ÷ 3 = 173,378.3333
If the quotient is a whole number, then 3 and 173,378.3333 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 | 520,135 | |
| -1 | -520,135 |
Let's try dividing by 4:
520,135 ÷ 4 = 130,033.75
If the quotient is a whole number, then 4 and 130,033.75 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 | 520,135 | |
| -1 | 520,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 49 | 55 | 77 | 193 | 245 | 385 | 539 | 965 | 1,351 | 2,123 | 2,695 | 6,755 | 9,457 | 10,615 | 14,861 | 47,285 | 74,305 | 104,027 | 520,135 |
| -1 | -5 | -7 | -11 | -35 | -49 | -55 | -77 | -193 | -245 | -385 | -539 | -965 | -1,351 | -2,123 | -2,695 | -6,755 | -9,457 | -10,615 | -14,861 | -47,285 | -74,305 | -104,027 | -520,135 |
