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 22,214,875, 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 | 22,214,875 | |
| -1 | -22,214,875 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,214,875.
Example:
1 x 22,214,875 = 22,214,875
and
-1 x -22,214,875 = 22,214,875
Notice both answers equal 22,214,875
With that explanation out of the way, let's continue. Next, we take the number 22,214,875 and divide it by 2:
22,214,875 ÷ 2 = 11,107,437.5
If the quotient is a whole number, then 2 and 11,107,437.5 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 | 22,214,875 | |
| -1 | -22,214,875 |
Now, we try dividing 22,214,875 by 3:
22,214,875 ÷ 3 = 7,404,958.3333
If the quotient is a whole number, then 3 and 7,404,958.3333 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 | 22,214,875 | |
| -1 | -22,214,875 |
Let's try dividing by 4:
22,214,875 ÷ 4 = 5,553,718.75
If the quotient is a whole number, then 4 and 5,553,718.75 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 | 22,214,875 | |
| -1 | 22,214,875 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 43 | 125 | 215 | 1,075 | 4,133 | 5,375 | 20,665 | 103,325 | 177,719 | 516,625 | 888,595 | 4,442,975 | 22,214,875 |
| -1 | -5 | -25 | -43 | -125 | -215 | -1,075 | -4,133 | -5,375 | -20,665 | -103,325 | -177,719 | -516,625 | -888,595 | -4,442,975 | -22,214,875 |
