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 22,056,221, 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 | 22,056,221 | |
| -1 | -22,056,221 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,056,221.
Example:
1 x 22,056,221 = 22,056,221
and
-1 x -22,056,221 = 22,056,221
Notice both answers equal 22,056,221
With that explanation out of the way, let's continue. Next, we take the number 22,056,221 and divide it by 2:
22,056,221 ÷ 2 = 11,028,110.5
If the quotient is a whole number, then 2 and 11,028,110.5 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 | 22,056,221 | |
| -1 | -22,056,221 |
Now, we try dividing 22,056,221 by 3:
22,056,221 ÷ 3 = 7,352,073.6667
If the quotient is a whole number, then 3 and 7,352,073.6667 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 | 22,056,221 | |
| -1 | -22,056,221 |
Let's try dividing by 4:
22,056,221 ÷ 4 = 5,514,055.25
If the quotient is a whole number, then 4 and 5,514,055.25 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 | 22,056,221 | |
| -1 | 22,056,221 |
If you did it right, you will end up with this table:
| 1 | 11 | 31 | 71 | 341 | 781 | 911 | 2,201 | 10,021 | 24,211 | 28,241 | 64,681 | 310,651 | 711,491 | 2,005,111 | 22,056,221 |
| -1 | -11 | -31 | -71 | -341 | -781 | -911 | -2,201 | -10,021 | -24,211 | -28,241 | -64,681 | -310,651 | -711,491 | -2,005,111 | -22,056,221 |
