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 22,272,019, 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 | 22,272,019 | |
| -1 | -22,272,019 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,272,019.
Example:
1 x 22,272,019 = 22,272,019
and
-1 x -22,272,019 = 22,272,019
Notice both answers equal 22,272,019
With that explanation out of the way, let's continue. Next, we take the number 22,272,019 and divide it by 2:
22,272,019 ÷ 2 = 11,136,009.5
If the quotient is a whole number, then 2 and 11,136,009.5 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 | 22,272,019 | |
| -1 | -22,272,019 |
Now, we try dividing 22,272,019 by 3:
22,272,019 ÷ 3 = 7,424,006.3333
If the quotient is a whole number, then 3 and 7,424,006.3333 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 | 22,272,019 | |
| -1 | -22,272,019 |
Let's try dividing by 4:
22,272,019 ÷ 4 = 5,568,004.75
If the quotient is a whole number, then 4 and 5,568,004.75 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 | 22,272,019 | |
| -1 | 22,272,019 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 49 | 77 | 343 | 539 | 3,773 | 5,903 | 41,321 | 64,933 | 289,247 | 454,531 | 2,024,729 | 3,181,717 | 22,272,019 |
| -1 | -7 | -11 | -49 | -77 | -343 | -539 | -3,773 | -5,903 | -41,321 | -64,933 | -289,247 | -454,531 | -2,024,729 | -3,181,717 | -22,272,019 |
