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 22,240,709, 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 | 22,240,709 | |
| -1 | -22,240,709 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,240,709.
Example:
1 x 22,240,709 = 22,240,709
and
-1 x -22,240,709 = 22,240,709
Notice both answers equal 22,240,709
With that explanation out of the way, let's continue. Next, we take the number 22,240,709 and divide it by 2:
22,240,709 ÷ 2 = 11,120,354.5
If the quotient is a whole number, then 2 and 11,120,354.5 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 | 22,240,709 | |
| -1 | -22,240,709 |
Now, we try dividing 22,240,709 by 3:
22,240,709 ÷ 3 = 7,413,569.6667
If the quotient is a whole number, then 3 and 7,413,569.6667 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 | 22,240,709 | |
| -1 | -22,240,709 |
Let's try dividing by 4:
22,240,709 ÷ 4 = 5,560,177.25
If the quotient is a whole number, then 4 and 5,560,177.25 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 | 22,240,709 | |
| -1 | 22,240,709 |
If you did it right, you will end up with this table:
| 1 | 17 | 29 | 197 | 229 | 493 | 3,349 | 3,893 | 5,713 | 6,641 | 45,113 | 97,121 | 112,897 | 766,921 | 1,308,277 | 22,240,709 |
| -1 | -17 | -29 | -197 | -229 | -493 | -3,349 | -3,893 | -5,713 | -6,641 | -45,113 | -97,121 | -112,897 | -766,921 | -1,308,277 | -22,240,709 |
