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 14,222,087, 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 | 14,222,087 | |
| -1 | -14,222,087 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,222,087.
Example:
1 x 14,222,087 = 14,222,087
and
-1 x -14,222,087 = 14,222,087
Notice both answers equal 14,222,087
With that explanation out of the way, let's continue. Next, we take the number 14,222,087 and divide it by 2:
14,222,087 ÷ 2 = 7,111,043.5
If the quotient is a whole number, then 2 and 7,111,043.5 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 | 14,222,087 | |
| -1 | -14,222,087 |
Now, we try dividing 14,222,087 by 3:
14,222,087 ÷ 3 = 4,740,695.6667
If the quotient is a whole number, then 3 and 4,740,695.6667 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 | 14,222,087 | |
| -1 | -14,222,087 |
Let's try dividing by 4:
14,222,087 ÷ 4 = 3,555,521.75
If the quotient is a whole number, then 4 and 3,555,521.75 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 | 14,222,087 | |
| -1 | 14,222,087 |
If you did it right, you will end up with this table:
| 1 | 11 | 31 | 179 | 233 | 341 | 1,969 | 2,563 | 5,549 | 7,223 | 41,707 | 61,039 | 79,453 | 458,777 | 1,292,917 | 14,222,087 |
| -1 | -11 | -31 | -179 | -233 | -341 | -1,969 | -2,563 | -5,549 | -7,223 | -41,707 | -61,039 | -79,453 | -458,777 | -1,292,917 | -14,222,087 |
