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 502,381,223, 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 | 502,381,223 | |
| -1 | -502,381,223 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 502,381,223.
Example:
1 x 502,381,223 = 502,381,223
and
-1 x -502,381,223 = 502,381,223
Notice both answers equal 502,381,223
With that explanation out of the way, let's continue. Next, we take the number 502,381,223 and divide it by 2:
502,381,223 ÷ 2 = 251,190,611.5
If the quotient is a whole number, then 2 and 251,190,611.5 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 | 502,381,223 | |
| -1 | -502,381,223 |
Now, we try dividing 502,381,223 by 3:
502,381,223 ÷ 3 = 167,460,407.6667
If the quotient is a whole number, then 3 and 167,460,407.6667 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 | 502,381,223 | |
| -1 | -502,381,223 |
Let's try dividing by 4:
502,381,223 ÷ 4 = 125,595,305.75
If the quotient is a whole number, then 4 and 125,595,305.75 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 | 502,381,223 | |
| -1 | 502,381,223 |
If you did it right, you will end up with this table:
| 1 | 19 | 53 | 1,007 | 2,809 | 9,413 | 53,371 | 178,847 | 498,889 | 9,478,891 | 26,441,117 | 502,381,223 |
| -1 | -19 | -53 | -1,007 | -2,809 | -9,413 | -53,371 | -178,847 | -498,889 | -9,478,891 | -26,441,117 | -502,381,223 |
