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 16,170,011, 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 | 16,170,011 | |
| -1 | -16,170,011 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,170,011.
Example:
1 x 16,170,011 = 16,170,011
and
-1 x -16,170,011 = 16,170,011
Notice both answers equal 16,170,011
With that explanation out of the way, let's continue. Next, we take the number 16,170,011 and divide it by 2:
16,170,011 ÷ 2 = 8,085,005.5
If the quotient is a whole number, then 2 and 8,085,005.5 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 | 16,170,011 | |
| -1 | -16,170,011 |
Now, we try dividing 16,170,011 by 3:
16,170,011 ÷ 3 = 5,390,003.6667
If the quotient is a whole number, then 3 and 5,390,003.6667 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 | 16,170,011 | |
| -1 | -16,170,011 |
Let's try dividing by 4:
16,170,011 ÷ 4 = 4,042,502.75
If the quotient is a whole number, then 4 and 4,042,502.75 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 | 16,170,011 | |
| -1 | 16,170,011 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 73 | 143 | 803 | 949 | 1,549 | 10,439 | 17,039 | 20,137 | 113,077 | 221,507 | 1,243,847 | 1,470,001 | 16,170,011 |
| -1 | -11 | -13 | -73 | -143 | -803 | -949 | -1,549 | -10,439 | -17,039 | -20,137 | -113,077 | -221,507 | -1,243,847 | -1,470,001 | -16,170,011 |
