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 16,853,515, 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 | 16,853,515 | |
| -1 | -16,853,515 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,853,515.
Example:
1 x 16,853,515 = 16,853,515
and
-1 x -16,853,515 = 16,853,515
Notice both answers equal 16,853,515
With that explanation out of the way, let's continue. Next, we take the number 16,853,515 and divide it by 2:
16,853,515 ÷ 2 = 8,426,757.5
If the quotient is a whole number, then 2 and 8,426,757.5 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 | 16,853,515 | |
| -1 | -16,853,515 |
Now, we try dividing 16,853,515 by 3:
16,853,515 ÷ 3 = 5,617,838.3333
If the quotient is a whole number, then 3 and 5,617,838.3333 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 | 16,853,515 | |
| -1 | -16,853,515 |
Let's try dividing by 4:
16,853,515 ÷ 4 = 4,213,378.75
If the quotient is a whole number, then 4 and 4,213,378.75 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 | 16,853,515 | |
| -1 | 16,853,515 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 67 | 335 | 469 | 2,345 | 7,187 | 35,935 | 50,309 | 251,545 | 481,529 | 2,407,645 | 3,370,703 | 16,853,515 |
| -1 | -5 | -7 | -35 | -67 | -335 | -469 | -2,345 | -7,187 | -35,935 | -50,309 | -251,545 | -481,529 | -2,407,645 | -3,370,703 | -16,853,515 |
