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 20,323,331, 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 | 20,323,331 | |
| -1 | -20,323,331 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 20,323,331.
Example:
1 x 20,323,331 = 20,323,331
and
-1 x -20,323,331 = 20,323,331
Notice both answers equal 20,323,331
With that explanation out of the way, let's continue. Next, we take the number 20,323,331 and divide it by 2:
20,323,331 ÷ 2 = 10,161,665.5
If the quotient is a whole number, then 2 and 10,161,665.5 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 | 20,323,331 | |
| -1 | -20,323,331 |
Now, we try dividing 20,323,331 by 3:
20,323,331 ÷ 3 = 6,774,443.6667
If the quotient is a whole number, then 3 and 6,774,443.6667 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 | 20,323,331 | |
| -1 | -20,323,331 |
Let's try dividing by 4:
20,323,331 ÷ 4 = 5,080,832.75
If the quotient is a whole number, then 4 and 5,080,832.75 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 | 20,323,331 | |
| -1 | 20,323,331 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 41 | 133 | 287 | 779 | 3,727 | 5,453 | 26,089 | 70,813 | 152,807 | 495,691 | 1,069,649 | 2,903,333 | 20,323,331 |
| -1 | -7 | -19 | -41 | -133 | -287 | -779 | -3,727 | -5,453 | -26,089 | -70,813 | -152,807 | -495,691 | -1,069,649 | -2,903,333 | -20,323,331 |
