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 512,352,439, 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 | 512,352,439 | |
| -1 | -512,352,439 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 512,352,439.
Example:
1 x 512,352,439 = 512,352,439
and
-1 x -512,352,439 = 512,352,439
Notice both answers equal 512,352,439
With that explanation out of the way, let's continue. Next, we take the number 512,352,439 and divide it by 2:
512,352,439 ÷ 2 = 256,176,219.5
If the quotient is a whole number, then 2 and 256,176,219.5 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 | 512,352,439 | |
| -1 | -512,352,439 |
Now, we try dividing 512,352,439 by 3:
512,352,439 ÷ 3 = 170,784,146.3333
If the quotient is a whole number, then 3 and 170,784,146.3333 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 | 512,352,439 | |
| -1 | -512,352,439 |
Let's try dividing by 4:
512,352,439 ÷ 4 = 128,088,109.75
If the quotient is a whole number, then 4 and 128,088,109.75 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 | 512,352,439 | |
| -1 | 512,352,439 |
If you did it right, you will end up with this table:
| 1 | 23 | 43 | 631 | 821 | 989 | 14,513 | 18,883 | 27,133 | 35,303 | 518,051 | 624,059 | 811,969 | 11,915,173 | 22,276,193 | 512,352,439 |
| -1 | -23 | -43 | -631 | -821 | -989 | -14,513 | -18,883 | -27,133 | -35,303 | -518,051 | -624,059 | -811,969 | -11,915,173 | -22,276,193 | -512,352,439 |
