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 14,212,445, 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 | 14,212,445 | |
| -1 | -14,212,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,212,445.
Example:
1 x 14,212,445 = 14,212,445
and
-1 x -14,212,445 = 14,212,445
Notice both answers equal 14,212,445
With that explanation out of the way, let's continue. Next, we take the number 14,212,445 and divide it by 2:
14,212,445 ÷ 2 = 7,106,222.5
If the quotient is a whole number, then 2 and 7,106,222.5 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 | 14,212,445 | |
| -1 | -14,212,445 |
Now, we try dividing 14,212,445 by 3:
14,212,445 ÷ 3 = 4,737,481.6667
If the quotient is a whole number, then 3 and 4,737,481.6667 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 | 14,212,445 | |
| -1 | -14,212,445 |
Let's try dividing by 4:
14,212,445 ÷ 4 = 3,553,111.25
If the quotient is a whole number, then 4 and 3,553,111.25 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 | 14,212,445 | |
| -1 | 14,212,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 41 | 65 | 205 | 533 | 2,665 | 5,333 | 26,665 | 69,329 | 218,653 | 346,645 | 1,093,265 | 2,842,489 | 14,212,445 |
| -1 | -5 | -13 | -41 | -65 | -205 | -533 | -2,665 | -5,333 | -26,665 | -69,329 | -218,653 | -346,645 | -1,093,265 | -2,842,489 | -14,212,445 |
