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 13,933,829, 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 | 13,933,829 | |
| -1 | -13,933,829 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,933,829.
Example:
1 x 13,933,829 = 13,933,829
and
-1 x -13,933,829 = 13,933,829
Notice both answers equal 13,933,829
With that explanation out of the way, let's continue. Next, we take the number 13,933,829 and divide it by 2:
13,933,829 ÷ 2 = 6,966,914.5
If the quotient is a whole number, then 2 and 6,966,914.5 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 | 13,933,829 | |
| -1 | -13,933,829 |
Now, we try dividing 13,933,829 by 3:
13,933,829 ÷ 3 = 4,644,609.6667
If the quotient is a whole number, then 3 and 4,644,609.6667 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 | 13,933,829 | |
| -1 | -13,933,829 |
Let's try dividing by 4:
13,933,829 ÷ 4 = 3,483,457.25
If the quotient is a whole number, then 4 and 3,483,457.25 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 | 13,933,829 | |
| -1 | 13,933,829 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 17 | 91 | 119 | 221 | 1,547 | 9,007 | 63,049 | 117,091 | 153,119 | 819,637 | 1,071,833 | 1,990,547 | 13,933,829 |
| -1 | -7 | -13 | -17 | -91 | -119 | -221 | -1,547 | -9,007 | -63,049 | -117,091 | -153,119 | -819,637 | -1,071,833 | -1,990,547 | -13,933,829 |
