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 201,321,131, 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 | 201,321,131 | |
| -1 | -201,321,131 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 201,321,131.
Example:
1 x 201,321,131 = 201,321,131
and
-1 x -201,321,131 = 201,321,131
Notice both answers equal 201,321,131
With that explanation out of the way, let's continue. Next, we take the number 201,321,131 and divide it by 2:
201,321,131 ÷ 2 = 100,660,565.5
If the quotient is a whole number, then 2 and 100,660,565.5 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 | 201,321,131 | |
| -1 | -201,321,131 |
Now, we try dividing 201,321,131 by 3:
201,321,131 ÷ 3 = 67,107,043.6667
If the quotient is a whole number, then 3 and 67,107,043.6667 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 | 201,321,131 | |
| -1 | -201,321,131 |
Let's try dividing by 4:
201,321,131 ÷ 4 = 50,330,282.75
If the quotient is a whole number, then 4 and 50,330,282.75 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 | 201,321,131 | |
| -1 | 201,321,131 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 67 | 121 | 209 | 737 | 1,273 | 1,307 | 2,299 | 8,107 | 14,003 | 14,377 | 24,833 | 87,569 | 154,033 | 158,147 | 273,163 | 963,259 | 1,663,811 | 3,004,793 | 10,595,849 | 18,301,921 | 201,321,131 |
| -1 | -11 | -19 | -67 | -121 | -209 | -737 | -1,273 | -1,307 | -2,299 | -8,107 | -14,003 | -14,377 | -24,833 | -87,569 | -154,033 | -158,147 | -273,163 | -963,259 | -1,663,811 | -3,004,793 | -10,595,849 | -18,301,921 | -201,321,131 |
