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 12,222,223, 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 | 12,222,223 | |
| -1 | -12,222,223 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,222,223.
Example:
1 x 12,222,223 = 12,222,223
and
-1 x -12,222,223 = 12,222,223
Notice both answers equal 12,222,223
With that explanation out of the way, let's continue. Next, we take the number 12,222,223 and divide it by 2:
12,222,223 ÷ 2 = 6,111,111.5
If the quotient is a whole number, then 2 and 6,111,111.5 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 | 12,222,223 | |
| -1 | -12,222,223 |
Now, we try dividing 12,222,223 by 3:
12,222,223 ÷ 3 = 4,074,074.3333
If the quotient is a whole number, then 3 and 4,074,074.3333 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 | 12,222,223 | |
| -1 | -12,222,223 |
Let's try dividing by 4:
12,222,223 ÷ 4 = 3,055,555.75
If the quotient is a whole number, then 4 and 3,055,555.75 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 | 12,222,223 | |
| -1 | 12,222,223 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 41 | 299 | 533 | 943 | 997 | 12,259 | 12,961 | 22,931 | 40,877 | 298,103 | 531,401 | 940,171 | 12,222,223 |
| -1 | -13 | -23 | -41 | -299 | -533 | -943 | -997 | -12,259 | -12,961 | -22,931 | -40,877 | -298,103 | -531,401 | -940,171 | -12,222,223 |
