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 520,429, 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 | 520,429 | |
| -1 | -520,429 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 520,429.
Example:
1 x 520,429 = 520,429
and
-1 x -520,429 = 520,429
Notice both answers equal 520,429
With that explanation out of the way, let's continue. Next, we take the number 520,429 and divide it by 2:
520,429 ÷ 2 = 260,214.5
If the quotient is a whole number, then 2 and 260,214.5 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 | 520,429 | |
| -1 | -520,429 |
Now, we try dividing 520,429 by 3:
520,429 ÷ 3 = 173,476.3333
If the quotient is a whole number, then 3 and 173,476.3333 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 | 520,429 | |
| -1 | -520,429 |
Let's try dividing by 4:
520,429 ÷ 4 = 130,107.25
If the quotient is a whole number, then 4 and 130,107.25 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 | 520,429 | |
| -1 | 520,429 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 19 | 43 | 49 | 91 | 133 | 247 | 301 | 559 | 637 | 817 | 931 | 1,729 | 2,107 | 3,913 | 5,719 | 10,621 | 12,103 | 27,391 | 40,033 | 74,347 | 520,429 |
| -1 | -7 | -13 | -19 | -43 | -49 | -91 | -133 | -247 | -301 | -559 | -637 | -817 | -931 | -1,729 | -2,107 | -3,913 | -5,719 | -10,621 | -12,103 | -27,391 | -40,033 | -74,347 | -520,429 |
