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 200,223,127, 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 | 200,223,127 | |
| -1 | -200,223,127 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 200,223,127.
Example:
1 x 200,223,127 = 200,223,127
and
-1 x -200,223,127 = 200,223,127
Notice both answers equal 200,223,127
With that explanation out of the way, let's continue. Next, we take the number 200,223,127 and divide it by 2:
200,223,127 ÷ 2 = 100,111,563.5
If the quotient is a whole number, then 2 and 100,111,563.5 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 | 200,223,127 | |
| -1 | -200,223,127 |
Now, we try dividing 200,223,127 by 3:
200,223,127 ÷ 3 = 66,741,042.3333
If the quotient is a whole number, then 3 and 66,741,042.3333 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 | 200,223,127 | |
| -1 | -200,223,127 |
Let's try dividing by 4:
200,223,127 ÷ 4 = 50,055,781.75
If the quotient is a whole number, then 4 and 50,055,781.75 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 | 200,223,127 | |
| -1 | 200,223,127 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 221 | 643 | 1,409 | 8,359 | 10,931 | 18,317 | 23,953 | 142,103 | 311,389 | 905,987 | 11,777,831 | 15,401,779 | 200,223,127 |
| -1 | -13 | -17 | -221 | -643 | -1,409 | -8,359 | -10,931 | -18,317 | -23,953 | -142,103 | -311,389 | -905,987 | -11,777,831 | -15,401,779 | -200,223,127 |
