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 12,222,301, 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 | 12,222,301 | |
| -1 | -12,222,301 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,222,301.
Example:
1 x 12,222,301 = 12,222,301
and
-1 x -12,222,301 = 12,222,301
Notice both answers equal 12,222,301
With that explanation out of the way, let's continue. Next, we take the number 12,222,301 and divide it by 2:
12,222,301 ÷ 2 = 6,111,150.5
If the quotient is a whole number, then 2 and 6,111,150.5 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 | 12,222,301 | |
| -1 | -12,222,301 |
Now, we try dividing 12,222,301 by 3:
12,222,301 ÷ 3 = 4,074,100.3333
If the quotient is a whole number, then 3 and 4,074,100.3333 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 | 12,222,301 | |
| -1 | -12,222,301 |
Let's try dividing by 4:
12,222,301 ÷ 4 = 3,055,575.25
If the quotient is a whole number, then 4 and 3,055,575.25 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 | 12,222,301 | |
| -1 | 12,222,301 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 19 | 91 | 133 | 247 | 1,729 | 7,069 | 49,483 | 91,897 | 134,311 | 643,279 | 940,177 | 1,746,043 | 12,222,301 |
| -1 | -7 | -13 | -19 | -91 | -133 | -247 | -1,729 | -7,069 | -49,483 | -91,897 | -134,311 | -643,279 | -940,177 | -1,746,043 | -12,222,301 |
