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 11,031,229, 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 | 11,031,229 | |
| -1 | -11,031,229 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,031,229.
Example:
1 x 11,031,229 = 11,031,229
and
-1 x -11,031,229 = 11,031,229
Notice both answers equal 11,031,229
With that explanation out of the way, let's continue. Next, we take the number 11,031,229 and divide it by 2:
11,031,229 ÷ 2 = 5,515,614.5
If the quotient is a whole number, then 2 and 5,515,614.5 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 | 11,031,229 | |
| -1 | -11,031,229 |
Now, we try dividing 11,031,229 by 3:
11,031,229 ÷ 3 = 3,677,076.3333
If the quotient is a whole number, then 3 and 3,677,076.3333 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 | 11,031,229 | |
| -1 | -11,031,229 |
Let's try dividing by 4:
11,031,229 ÷ 4 = 2,757,807.25
If the quotient is a whole number, then 4 and 2,757,807.25 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 | 11,031,229 | |
| -1 | 11,031,229 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 47 | 209 | 517 | 893 | 1,123 | 9,823 | 12,353 | 21,337 | 52,781 | 234,707 | 580,591 | 1,002,839 | 11,031,229 |
| -1 | -11 | -19 | -47 | -209 | -517 | -893 | -1,123 | -9,823 | -12,353 | -21,337 | -52,781 | -234,707 | -580,591 | -1,002,839 | -11,031,229 |
