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 22,057,217, 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 | 22,057,217 | |
| -1 | -22,057,217 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,057,217.
Example:
1 x 22,057,217 = 22,057,217
and
-1 x -22,057,217 = 22,057,217
Notice both answers equal 22,057,217
With that explanation out of the way, let's continue. Next, we take the number 22,057,217 and divide it by 2:
22,057,217 ÷ 2 = 11,028,608.5
If the quotient is a whole number, then 2 and 11,028,608.5 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 | 22,057,217 | |
| -1 | -22,057,217 |
Now, we try dividing 22,057,217 by 3:
22,057,217 ÷ 3 = 7,352,405.6667
If the quotient is a whole number, then 3 and 7,352,405.6667 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 | 22,057,217 | |
| -1 | -22,057,217 |
Let's try dividing by 4:
22,057,217 ÷ 4 = 5,514,304.25
If the quotient is a whole number, then 4 and 5,514,304.25 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 | 22,057,217 | |
| -1 | 22,057,217 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 37 | 91 | 259 | 481 | 3,367 | 6,551 | 45,857 | 85,163 | 242,387 | 596,141 | 1,696,709 | 3,151,031 | 22,057,217 |
| -1 | -7 | -13 | -37 | -91 | -259 | -481 | -3,367 | -6,551 | -45,857 | -85,163 | -242,387 | -596,141 | -1,696,709 | -3,151,031 | -22,057,217 |
