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 22,011,605, 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 | 22,011,605 | |
| -1 | -22,011,605 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,011,605.
Example:
1 x 22,011,605 = 22,011,605
and
-1 x -22,011,605 = 22,011,605
Notice both answers equal 22,011,605
With that explanation out of the way, let's continue. Next, we take the number 22,011,605 and divide it by 2:
22,011,605 ÷ 2 = 11,005,802.5
If the quotient is a whole number, then 2 and 11,005,802.5 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 | 22,011,605 | |
| -1 | -22,011,605 |
Now, we try dividing 22,011,605 by 3:
22,011,605 ÷ 3 = 7,337,201.6667
If the quotient is a whole number, then 3 and 7,337,201.6667 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 | 22,011,605 | |
| -1 | -22,011,605 |
Let's try dividing by 4:
22,011,605 ÷ 4 = 5,502,901.25
If the quotient is a whole number, then 4 and 5,502,901.25 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 | 22,011,605 | |
| -1 | 22,011,605 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 55 | 77 | 385 | 57,173 | 285,865 | 400,211 | 628,903 | 2,001,055 | 3,144,515 | 4,402,321 | 22,011,605 |
| -1 | -5 | -7 | -11 | -35 | -55 | -77 | -385 | -57,173 | -285,865 | -400,211 | -628,903 | -2,001,055 | -3,144,515 | -4,402,321 | -22,011,605 |
