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 16,631,111, 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 | 16,631,111 | |
| -1 | -16,631,111 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,631,111.
Example:
1 x 16,631,111 = 16,631,111
and
-1 x -16,631,111 = 16,631,111
Notice both answers equal 16,631,111
With that explanation out of the way, let's continue. Next, we take the number 16,631,111 and divide it by 2:
16,631,111 ÷ 2 = 8,315,555.5
If the quotient is a whole number, then 2 and 8,315,555.5 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 | 16,631,111 | |
| -1 | -16,631,111 |
Now, we try dividing 16,631,111 by 3:
16,631,111 ÷ 3 = 5,543,703.6667
If the quotient is a whole number, then 3 and 5,543,703.6667 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 | 16,631,111 | |
| -1 | -16,631,111 |
Let's try dividing by 4:
16,631,111 ÷ 4 = 4,157,777.75
If the quotient is a whole number, then 4 and 4,157,777.75 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 | 16,631,111 | |
| -1 | 16,631,111 |
If you did it right, you will end up with this table:
| 1 | 7 | 71 | 109 | 307 | 497 | 763 | 2,149 | 7,739 | 21,797 | 33,463 | 54,173 | 152,579 | 234,241 | 2,375,873 | 16,631,111 |
| -1 | -7 | -71 | -109 | -307 | -497 | -763 | -2,149 | -7,739 | -21,797 | -33,463 | -54,173 | -152,579 | -234,241 | -2,375,873 | -16,631,111 |
