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 11,113,223, 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 | 11,113,223 | |
| -1 | -11,113,223 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,113,223.
Example:
1 x 11,113,223 = 11,113,223
and
-1 x -11,113,223 = 11,113,223
Notice both answers equal 11,113,223
With that explanation out of the way, let's continue. Next, we take the number 11,113,223 and divide it by 2:
11,113,223 ÷ 2 = 5,556,611.5
If the quotient is a whole number, then 2 and 5,556,611.5 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 | 11,113,223 | |
| -1 | -11,113,223 |
Now, we try dividing 11,113,223 by 3:
11,113,223 ÷ 3 = 3,704,407.6667
If the quotient is a whole number, then 3 and 3,704,407.6667 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 | 11,113,223 | |
| -1 | -11,113,223 |
Let's try dividing by 4:
11,113,223 ÷ 4 = 2,778,305.75
If the quotient is a whole number, then 4 and 2,778,305.75 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 | 11,113,223 | |
| -1 | 11,113,223 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 67 | 187 | 737 | 887 | 1,139 | 9,757 | 12,529 | 15,079 | 59,429 | 165,869 | 653,719 | 1,010,293 | 11,113,223 |
| -1 | -11 | -17 | -67 | -187 | -737 | -887 | -1,139 | -9,757 | -12,529 | -15,079 | -59,429 | -165,869 | -653,719 | -1,010,293 | -11,113,223 |
