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 12,228,229, 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 | 12,228,229 | |
| -1 | -12,228,229 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,228,229.
Example:
1 x 12,228,229 = 12,228,229
and
-1 x -12,228,229 = 12,228,229
Notice both answers equal 12,228,229
With that explanation out of the way, let's continue. Next, we take the number 12,228,229 and divide it by 2:
12,228,229 ÷ 2 = 6,114,114.5
If the quotient is a whole number, then 2 and 6,114,114.5 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 | 12,228,229 | |
| -1 | -12,228,229 |
Now, we try dividing 12,228,229 by 3:
12,228,229 ÷ 3 = 4,076,076.3333
If the quotient is a whole number, then 3 and 4,076,076.3333 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 | 12,228,229 | |
| -1 | -12,228,229 |
Let's try dividing by 4:
12,228,229 ÷ 4 = 3,057,057.25
If the quotient is a whole number, then 4 and 3,057,057.25 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 | 12,228,229 | |
| -1 | 12,228,229 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 31 | 247 | 403 | 589 | 1,597 | 7,657 | 20,761 | 30,343 | 49,507 | 394,459 | 643,591 | 940,633 | 12,228,229 |
| -1 | -13 | -19 | -31 | -247 | -403 | -589 | -1,597 | -7,657 | -20,761 | -30,343 | -49,507 | -394,459 | -643,591 | -940,633 | -12,228,229 |
