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 22,018,315, 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 | 22,018,315 | |
| -1 | -22,018,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,018,315.
Example:
1 x 22,018,315 = 22,018,315
and
-1 x -22,018,315 = 22,018,315
Notice both answers equal 22,018,315
With that explanation out of the way, let's continue. Next, we take the number 22,018,315 and divide it by 2:
22,018,315 ÷ 2 = 11,009,157.5
If the quotient is a whole number, then 2 and 11,009,157.5 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 | 22,018,315 | |
| -1 | -22,018,315 |
Now, we try dividing 22,018,315 by 3:
22,018,315 ÷ 3 = 7,339,438.3333
If the quotient is a whole number, then 3 and 7,339,438.3333 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 | 22,018,315 | |
| -1 | -22,018,315 |
Let's try dividing by 4:
22,018,315 ÷ 4 = 5,504,578.75
If the quotient is a whole number, then 4 and 5,504,578.75 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 | 22,018,315 | |
| -1 | 22,018,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 17 | 55 | 85 | 187 | 935 | 23,549 | 117,745 | 259,039 | 400,333 | 1,295,195 | 2,001,665 | 4,403,663 | 22,018,315 |
| -1 | -5 | -11 | -17 | -55 | -85 | -187 | -935 | -23,549 | -117,745 | -259,039 | -400,333 | -1,295,195 | -2,001,665 | -4,403,663 | -22,018,315 |
