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 16,016,351, 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 | 16,016,351 | |
| -1 | -16,016,351 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,016,351.
Example:
1 x 16,016,351 = 16,016,351
and
-1 x -16,016,351 = 16,016,351
Notice both answers equal 16,016,351
With that explanation out of the way, let's continue. Next, we take the number 16,016,351 and divide it by 2:
16,016,351 ÷ 2 = 8,008,175.5
If the quotient is a whole number, then 2 and 8,008,175.5 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 | 16,016,351 | |
| -1 | -16,016,351 |
Now, we try dividing 16,016,351 by 3:
16,016,351 ÷ 3 = 5,338,783.6667
If the quotient is a whole number, then 3 and 5,338,783.6667 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 | 16,016,351 | |
| -1 | -16,016,351 |
Let's try dividing by 4:
16,016,351 ÷ 4 = 4,004,087.75
If the quotient is a whole number, then 4 and 4,004,087.75 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 | 16,016,351 | |
| -1 | 16,016,351 |
If you did it right, you will end up with this table:
| 1 | 13 | 89 | 109 | 127 | 1,157 | 1,417 | 1,651 | 9,701 | 11,303 | 13,843 | 126,113 | 146,939 | 179,959 | 1,232,027 | 16,016,351 |
| -1 | -13 | -89 | -109 | -127 | -1,157 | -1,417 | -1,651 | -9,701 | -11,303 | -13,843 | -126,113 | -146,939 | -179,959 | -1,232,027 | -16,016,351 |
