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 12,223,099, 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 | 12,223,099 | |
| -1 | -12,223,099 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,223,099.
Example:
1 x 12,223,099 = 12,223,099
and
-1 x -12,223,099 = 12,223,099
Notice both answers equal 12,223,099
With that explanation out of the way, let's continue. Next, we take the number 12,223,099 and divide it by 2:
12,223,099 ÷ 2 = 6,111,549.5
If the quotient is a whole number, then 2 and 6,111,549.5 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 | 12,223,099 | |
| -1 | -12,223,099 |
Now, we try dividing 12,223,099 by 3:
12,223,099 ÷ 3 = 4,074,366.3333
If the quotient is a whole number, then 3 and 4,074,366.3333 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 | 12,223,099 | |
| -1 | -12,223,099 |
Let's try dividing by 4:
12,223,099 ÷ 4 = 3,055,774.75
If the quotient is a whole number, then 4 and 3,055,774.75 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 | 12,223,099 | |
| -1 | 12,223,099 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 49 | 133 | 361 | 691 | 931 | 2,527 | 4,837 | 13,129 | 17,689 | 33,859 | 91,903 | 249,451 | 643,321 | 1,746,157 | 12,223,099 |
| -1 | -7 | -19 | -49 | -133 | -361 | -691 | -931 | -2,527 | -4,837 | -13,129 | -17,689 | -33,859 | -91,903 | -249,451 | -643,321 | -1,746,157 | -12,223,099 |
