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 16,006,111, 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 | 16,006,111 | |
| -1 | -16,006,111 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,006,111.
Example:
1 x 16,006,111 = 16,006,111
and
-1 x -16,006,111 = 16,006,111
Notice both answers equal 16,006,111
With that explanation out of the way, let's continue. Next, we take the number 16,006,111 and divide it by 2:
16,006,111 ÷ 2 = 8,003,055.5
If the quotient is a whole number, then 2 and 8,003,055.5 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 | 16,006,111 | |
| -1 | -16,006,111 |
Now, we try dividing 16,006,111 by 3:
16,006,111 ÷ 3 = 5,335,370.3333
If the quotient is a whole number, then 3 and 5,335,370.3333 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 | 16,006,111 | |
| -1 | -16,006,111 |
Let's try dividing by 4:
16,006,111 ÷ 4 = 4,001,527.75
If the quotient is a whole number, then 4 and 4,001,527.75 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 | 16,006,111 | |
| -1 | 16,006,111 |
If you did it right, you will end up with this table:
| 1 | 11 | 79 | 113 | 163 | 869 | 1,243 | 1,793 | 8,927 | 12,877 | 18,419 | 98,197 | 141,647 | 202,609 | 1,455,101 | 16,006,111 |
| -1 | -11 | -79 | -113 | -163 | -869 | -1,243 | -1,793 | -8,927 | -12,877 | -18,419 | -98,197 | -141,647 | -202,609 | -1,455,101 | -16,006,111 |
