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 200,223,331, 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 | 200,223,331 | |
| -1 | -200,223,331 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 200,223,331.
Example:
1 x 200,223,331 = 200,223,331
and
-1 x -200,223,331 = 200,223,331
Notice both answers equal 200,223,331
With that explanation out of the way, let's continue. Next, we take the number 200,223,331 and divide it by 2:
200,223,331 ÷ 2 = 100,111,665.5
If the quotient is a whole number, then 2 and 100,111,665.5 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 | 200,223,331 | |
| -1 | -200,223,331 |
Now, we try dividing 200,223,331 by 3:
200,223,331 ÷ 3 = 66,741,110.3333
If the quotient is a whole number, then 3 and 66,741,110.3333 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 | 200,223,331 | |
| -1 | -200,223,331 |
Let's try dividing by 4:
200,223,331 ÷ 4 = 50,055,832.75
If the quotient is a whole number, then 4 and 50,055,832.75 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 | 200,223,331 | |
| -1 | 200,223,331 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 17 | 77 | 119 | 187 | 1,309 | 152,959 | 1,070,713 | 1,682,549 | 2,600,303 | 11,777,843 | 18,202,121 | 28,603,333 | 200,223,331 |
| -1 | -7 | -11 | -17 | -77 | -119 | -187 | -1,309 | -152,959 | -1,070,713 | -1,682,549 | -2,600,303 | -11,777,843 | -18,202,121 | -28,603,333 | -200,223,331 |
