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 13,808,333, 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 | 13,808,333 | |
| -1 | -13,808,333 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,808,333.
Example:
1 x 13,808,333 = 13,808,333
and
-1 x -13,808,333 = 13,808,333
Notice both answers equal 13,808,333
With that explanation out of the way, let's continue. Next, we take the number 13,808,333 and divide it by 2:
13,808,333 ÷ 2 = 6,904,166.5
If the quotient is a whole number, then 2 and 6,904,166.5 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 | 13,808,333 | |
| -1 | -13,808,333 |
Now, we try dividing 13,808,333 by 3:
13,808,333 ÷ 3 = 4,602,777.6667
If the quotient is a whole number, then 3 and 4,602,777.6667 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 | 13,808,333 | |
| -1 | -13,808,333 |
Let's try dividing by 4:
13,808,333 ÷ 4 = 3,452,083.25
If the quotient is a whole number, then 4 and 3,452,083.25 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 | 13,808,333 | |
| -1 | 13,808,333 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 389 | 461 | 2,723 | 3,227 | 4,279 | 5,071 | 29,953 | 35,497 | 179,329 | 1,255,303 | 1,972,619 | 13,808,333 |
| -1 | -7 | -11 | -77 | -389 | -461 | -2,723 | -3,227 | -4,279 | -5,071 | -29,953 | -35,497 | -179,329 | -1,255,303 | -1,972,619 | -13,808,333 |
