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 13,395,833, 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 | 13,395,833 | |
| -1 | -13,395,833 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,395,833.
Example:
1 x 13,395,833 = 13,395,833
and
-1 x -13,395,833 = 13,395,833
Notice both answers equal 13,395,833
With that explanation out of the way, let's continue. Next, we take the number 13,395,833 and divide it by 2:
13,395,833 ÷ 2 = 6,697,916.5
If the quotient is a whole number, then 2 and 6,697,916.5 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 | 13,395,833 | |
| -1 | -13,395,833 |
Now, we try dividing 13,395,833 by 3:
13,395,833 ÷ 3 = 4,465,277.6667
If the quotient is a whole number, then 3 and 4,465,277.6667 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 | 13,395,833 | |
| -1 | -13,395,833 |
Let's try dividing by 4:
13,395,833 ÷ 4 = 3,348,958.25
If the quotient is a whole number, then 4 and 3,348,958.25 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 | 13,395,833 | |
| -1 | 13,395,833 |
If you did it right, you will end up with this table:
| 1 | 11 | 43 | 127 | 223 | 473 | 1,397 | 2,453 | 5,461 | 9,589 | 28,321 | 60,071 | 105,479 | 311,531 | 1,217,803 | 13,395,833 |
| -1 | -11 | -43 | -127 | -223 | -473 | -1,397 | -2,453 | -5,461 | -9,589 | -28,321 | -60,071 | -105,479 | -311,531 | -1,217,803 | -13,395,833 |
