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 22,414,021, 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 | 22,414,021 | |
| -1 | -22,414,021 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,414,021.
Example:
1 x 22,414,021 = 22,414,021
and
-1 x -22,414,021 = 22,414,021
Notice both answers equal 22,414,021
With that explanation out of the way, let's continue. Next, we take the number 22,414,021 and divide it by 2:
22,414,021 ÷ 2 = 11,207,010.5
If the quotient is a whole number, then 2 and 11,207,010.5 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 | 22,414,021 | |
| -1 | -22,414,021 |
Now, we try dividing 22,414,021 by 3:
22,414,021 ÷ 3 = 7,471,340.3333
If the quotient is a whole number, then 3 and 7,471,340.3333 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 | 22,414,021 | |
| -1 | -22,414,021 |
Let's try dividing by 4:
22,414,021 ÷ 4 = 5,603,505.25
If the quotient is a whole number, then 4 and 5,603,505.25 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 | 22,414,021 | |
| -1 | 22,414,021 |
If you did it right, you will end up with this table:
| 1 | 7 | 49 | 101 | 343 | 647 | 707 | 4,529 | 4,949 | 31,703 | 34,643 | 65,347 | 221,921 | 457,429 | 3,202,003 | 22,414,021 |
| -1 | -7 | -49 | -101 | -343 | -647 | -707 | -4,529 | -4,949 | -31,703 | -34,643 | -65,347 | -221,921 | -457,429 | -3,202,003 | -22,414,021 |
