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 14,344,421, 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 | 14,344,421 | |
| -1 | -14,344,421 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,344,421.
Example:
1 x 14,344,421 = 14,344,421
and
-1 x -14,344,421 = 14,344,421
Notice both answers equal 14,344,421
With that explanation out of the way, let's continue. Next, we take the number 14,344,421 and divide it by 2:
14,344,421 ÷ 2 = 7,172,210.5
If the quotient is a whole number, then 2 and 7,172,210.5 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 | 14,344,421 | |
| -1 | -14,344,421 |
Now, we try dividing 14,344,421 by 3:
14,344,421 ÷ 3 = 4,781,473.6667
If the quotient is a whole number, then 3 and 4,781,473.6667 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 | 14,344,421 | |
| -1 | -14,344,421 |
Let's try dividing by 4:
14,344,421 ÷ 4 = 3,586,105.25
If the quotient is a whole number, then 4 and 3,586,105.25 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 | 14,344,421 | |
| -1 | 14,344,421 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 283 | 557 | 1,981 | 3,679 | 3,899 | 7,241 | 25,753 | 50,687 | 157,631 | 1,103,417 | 2,049,203 | 14,344,421 |
| -1 | -7 | -13 | -91 | -283 | -557 | -1,981 | -3,679 | -3,899 | -7,241 | -25,753 | -50,687 | -157,631 | -1,103,417 | -2,049,203 | -14,344,421 |
