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 11,000,015, 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 | 11,000,015 | |
| -1 | -11,000,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,000,015.
Example:
1 x 11,000,015 = 11,000,015
and
-1 x -11,000,015 = 11,000,015
Notice both answers equal 11,000,015
With that explanation out of the way, let's continue. Next, we take the number 11,000,015 and divide it by 2:
11,000,015 ÷ 2 = 5,500,007.5
If the quotient is a whole number, then 2 and 5,500,007.5 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 | 11,000,015 | |
| -1 | -11,000,015 |
Now, we try dividing 11,000,015 by 3:
11,000,015 ÷ 3 = 3,666,671.6667
If the quotient is a whole number, then 3 and 3,666,671.6667 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 | 11,000,015 | |
| -1 | -11,000,015 |
Let's try dividing by 4:
11,000,015 ÷ 4 = 2,750,003.75
If the quotient is a whole number, then 4 and 2,750,003.75 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 | 11,000,015 | |
| -1 | 11,000,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 229 | 739 | 1,145 | 2,977 | 3,695 | 9,607 | 14,885 | 48,035 | 169,231 | 846,155 | 2,200,003 | 11,000,015 |
| -1 | -5 | -13 | -65 | -229 | -739 | -1,145 | -2,977 | -3,695 | -9,607 | -14,885 | -48,035 | -169,231 | -846,155 | -2,200,003 | -11,000,015 |
