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 324,020,203, 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 | 324,020,203 | |
| -1 | -324,020,203 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 324,020,203.
Example:
1 x 324,020,203 = 324,020,203
and
-1 x -324,020,203 = 324,020,203
Notice both answers equal 324,020,203
With that explanation out of the way, let's continue. Next, we take the number 324,020,203 and divide it by 2:
324,020,203 ÷ 2 = 162,010,101.5
If the quotient is a whole number, then 2 and 162,010,101.5 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 | 324,020,203 | |
| -1 | -324,020,203 |
Now, we try dividing 324,020,203 by 3:
324,020,203 ÷ 3 = 108,006,734.3333
If the quotient is a whole number, then 3 and 108,006,734.3333 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 | 324,020,203 | |
| -1 | -324,020,203 |
Let's try dividing by 4:
324,020,203 ÷ 4 = 81,005,050.75
If the quotient is a whole number, then 4 and 81,005,050.75 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 | 324,020,203 | |
| -1 | 324,020,203 |
If you did it right, you will end up with this table:
| 1 | 13 | 257 | 293 | 331 | 3,341 | 3,809 | 4,303 | 75,301 | 85,067 | 96,983 | 978,913 | 1,105,871 | 1,260,779 | 24,924,631 | 324,020,203 |
| -1 | -13 | -257 | -293 | -331 | -3,341 | -3,809 | -4,303 | -75,301 | -85,067 | -96,983 | -978,913 | -1,105,871 | -1,260,779 | -24,924,631 | -324,020,203 |
