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 14,212,135, 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 | 14,212,135 | |
| -1 | -14,212,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,212,135.
Example:
1 x 14,212,135 = 14,212,135
and
-1 x -14,212,135 = 14,212,135
Notice both answers equal 14,212,135
With that explanation out of the way, let's continue. Next, we take the number 14,212,135 and divide it by 2:
14,212,135 ÷ 2 = 7,106,067.5
If the quotient is a whole number, then 2 and 7,106,067.5 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 | 14,212,135 | |
| -1 | -14,212,135 |
Now, we try dividing 14,212,135 by 3:
14,212,135 ÷ 3 = 4,737,378.3333
If the quotient is a whole number, then 3 and 4,737,378.3333 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 | 14,212,135 | |
| -1 | -14,212,135 |
Let's try dividing by 4:
14,212,135 ÷ 4 = 3,553,033.75
If the quotient is a whole number, then 4 and 3,553,033.75 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 | 14,212,135 | |
| -1 | 14,212,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 239 | 1,195 | 1,673 | 1,699 | 8,365 | 8,495 | 11,893 | 59,465 | 406,061 | 2,030,305 | 2,842,427 | 14,212,135 |
| -1 | -5 | -7 | -35 | -239 | -1,195 | -1,673 | -1,699 | -8,365 | -8,495 | -11,893 | -59,465 | -406,061 | -2,030,305 | -2,842,427 | -14,212,135 |
