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 13,214,443, 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 | 13,214,443 | |
| -1 | -13,214,443 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,214,443.
Example:
1 x 13,214,443 = 13,214,443
and
-1 x -13,214,443 = 13,214,443
Notice both answers equal 13,214,443
With that explanation out of the way, let's continue. Next, we take the number 13,214,443 and divide it by 2:
13,214,443 ÷ 2 = 6,607,221.5
If the quotient is a whole number, then 2 and 6,607,221.5 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 | 13,214,443 | |
| -1 | -13,214,443 |
Now, we try dividing 13,214,443 by 3:
13,214,443 ÷ 3 = 4,404,814.3333
If the quotient is a whole number, then 3 and 4,404,814.3333 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 | 13,214,443 | |
| -1 | -13,214,443 |
Let's try dividing by 4:
13,214,443 ÷ 4 = 3,303,610.75
If the quotient is a whole number, then 4 and 3,303,610.75 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 | 13,214,443 | |
| -1 | 13,214,443 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 23 | 209 | 253 | 437 | 2,749 | 4,807 | 30,239 | 52,231 | 63,227 | 574,541 | 695,497 | 1,201,313 | 13,214,443 |
| -1 | -11 | -19 | -23 | -209 | -253 | -437 | -2,749 | -4,807 | -30,239 | -52,231 | -63,227 | -574,541 | -695,497 | -1,201,313 | -13,214,443 |
