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 16,116,835, 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 | 16,116,835 | |
| -1 | -16,116,835 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,116,835.
Example:
1 x 16,116,835 = 16,116,835
and
-1 x -16,116,835 = 16,116,835
Notice both answers equal 16,116,835
With that explanation out of the way, let's continue. Next, we take the number 16,116,835 and divide it by 2:
16,116,835 ÷ 2 = 8,058,417.5
If the quotient is a whole number, then 2 and 8,058,417.5 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 | 16,116,835 | |
| -1 | -16,116,835 |
Now, we try dividing 16,116,835 by 3:
16,116,835 ÷ 3 = 5,372,278.3333
If the quotient is a whole number, then 3 and 5,372,278.3333 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 | 16,116,835 | |
| -1 | -16,116,835 |
Let's try dividing by 4:
16,116,835 ÷ 4 = 4,029,208.75
If the quotient is a whole number, then 4 and 4,029,208.75 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 | 16,116,835 | |
| -1 | 16,116,835 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 157 | 245 | 419 | 785 | 1,099 | 2,095 | 2,933 | 5,495 | 7,693 | 14,665 | 20,531 | 38,465 | 65,783 | 102,655 | 328,915 | 460,481 | 2,302,405 | 3,223,367 | 16,116,835 |
| -1 | -5 | -7 | -35 | -49 | -157 | -245 | -419 | -785 | -1,099 | -2,095 | -2,933 | -5,495 | -7,693 | -14,665 | -20,531 | -38,465 | -65,783 | -102,655 | -328,915 | -460,481 | -2,302,405 | -3,223,367 | -16,116,835 |
