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 16,006,735, 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 | 16,006,735 | |
| -1 | -16,006,735 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,006,735.
Example:
1 x 16,006,735 = 16,006,735
and
-1 x -16,006,735 = 16,006,735
Notice both answers equal 16,006,735
With that explanation out of the way, let's continue. Next, we take the number 16,006,735 and divide it by 2:
16,006,735 ÷ 2 = 8,003,367.5
If the quotient is a whole number, then 2 and 8,003,367.5 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 | 16,006,735 | |
| -1 | -16,006,735 |
Now, we try dividing 16,006,735 by 3:
16,006,735 ÷ 3 = 5,335,578.3333
If the quotient is a whole number, then 3 and 5,335,578.3333 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 | 16,006,735 | |
| -1 | -16,006,735 |
Let's try dividing by 4:
16,006,735 ÷ 4 = 4,001,683.75
If the quotient is a whole number, then 4 and 4,001,683.75 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 | 16,006,735 | |
| -1 | 16,006,735 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 181 | 769 | 905 | 3,845 | 4,163 | 17,687 | 20,815 | 88,435 | 139,189 | 695,945 | 3,201,347 | 16,006,735 |
| -1 | -5 | -23 | -115 | -181 | -769 | -905 | -3,845 | -4,163 | -17,687 | -20,815 | -88,435 | -139,189 | -695,945 | -3,201,347 | -16,006,735 |
