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 12,220,195, 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 | 12,220,195 | |
| -1 | -12,220,195 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,220,195.
Example:
1 x 12,220,195 = 12,220,195
and
-1 x -12,220,195 = 12,220,195
Notice both answers equal 12,220,195
With that explanation out of the way, let's continue. Next, we take the number 12,220,195 and divide it by 2:
12,220,195 ÷ 2 = 6,110,097.5
If the quotient is a whole number, then 2 and 6,110,097.5 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 | 12,220,195 | |
| -1 | -12,220,195 |
Now, we try dividing 12,220,195 by 3:
12,220,195 ÷ 3 = 4,073,398.3333
If the quotient is a whole number, then 3 and 4,073,398.3333 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 | 12,220,195 | |
| -1 | -12,220,195 |
Let's try dividing by 4:
12,220,195 ÷ 4 = 3,055,048.75
If the quotient is a whole number, then 4 and 3,055,048.75 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 | 12,220,195 | |
| -1 | 12,220,195 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 17 | 65 | 85 | 221 | 1,105 | 11,059 | 55,295 | 143,767 | 188,003 | 718,835 | 940,015 | 2,444,039 | 12,220,195 |
| -1 | -5 | -13 | -17 | -65 | -85 | -221 | -1,105 | -11,059 | -55,295 | -143,767 | -188,003 | -718,835 | -940,015 | -2,444,039 | -12,220,195 |
