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 13,816,835, 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 | 13,816,835 | |
| -1 | -13,816,835 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,816,835.
Example:
1 x 13,816,835 = 13,816,835
and
-1 x -13,816,835 = 13,816,835
Notice both answers equal 13,816,835
With that explanation out of the way, let's continue. Next, we take the number 13,816,835 and divide it by 2:
13,816,835 ÷ 2 = 6,908,417.5
If the quotient is a whole number, then 2 and 6,908,417.5 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 | 13,816,835 | |
| -1 | -13,816,835 |
Now, we try dividing 13,816,835 by 3:
13,816,835 ÷ 3 = 4,605,611.6667
If the quotient is a whole number, then 3 and 4,605,611.6667 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 | 13,816,835 | |
| -1 | -13,816,835 |
Let's try dividing by 4:
13,816,835 ÷ 4 = 3,454,208.75
If the quotient is a whole number, then 4 and 3,454,208.75 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 | 13,816,835 | |
| -1 | 13,816,835 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 53 | 85 | 265 | 901 | 3,067 | 4,505 | 15,335 | 52,139 | 162,551 | 260,695 | 812,755 | 2,763,367 | 13,816,835 |
| -1 | -5 | -17 | -53 | -85 | -265 | -901 | -3,067 | -4,505 | -15,335 | -52,139 | -162,551 | -260,695 | -812,755 | -2,763,367 | -13,816,835 |
