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 502,511,345, 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 | 502,511,345 | |
| -1 | -502,511,345 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 502,511,345.
Example:
1 x 502,511,345 = 502,511,345
and
-1 x -502,511,345 = 502,511,345
Notice both answers equal 502,511,345
With that explanation out of the way, let's continue. Next, we take the number 502,511,345 and divide it by 2:
502,511,345 ÷ 2 = 251,255,672.5
If the quotient is a whole number, then 2 and 251,255,672.5 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 | 502,511,345 | |
| -1 | -502,511,345 |
Now, we try dividing 502,511,345 by 3:
502,511,345 ÷ 3 = 167,503,781.6667
If the quotient is a whole number, then 3 and 167,503,781.6667 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 | 502,511,345 | |
| -1 | -502,511,345 |
Let's try dividing by 4:
502,511,345 ÷ 4 = 125,627,836.25
If the quotient is a whole number, then 4 and 125,627,836.25 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 | 502,511,345 | |
| -1 | 502,511,345 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 947 | 4,735 | 6,629 | 15,161 | 33,145 | 75,805 | 106,127 | 530,635 | 14,357,467 | 71,787,335 | 100,502,269 | 502,511,345 |
| -1 | -5 | -7 | -35 | -947 | -4,735 | -6,629 | -15,161 | -33,145 | -75,805 | -106,127 | -530,635 | -14,357,467 | -71,787,335 | -100,502,269 | -502,511,345 |
