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 14,405,413, 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 | 14,405,413 | |
| -1 | -14,405,413 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,405,413.
Example:
1 x 14,405,413 = 14,405,413
and
-1 x -14,405,413 = 14,405,413
Notice both answers equal 14,405,413
With that explanation out of the way, let's continue. Next, we take the number 14,405,413 and divide it by 2:
14,405,413 ÷ 2 = 7,202,706.5
If the quotient is a whole number, then 2 and 7,202,706.5 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 | 14,405,413 | |
| -1 | -14,405,413 |
Now, we try dividing 14,405,413 by 3:
14,405,413 ÷ 3 = 4,801,804.3333
If the quotient is a whole number, then 3 and 4,801,804.3333 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 | 14,405,413 | |
| -1 | -14,405,413 |
Let's try dividing by 4:
14,405,413 ÷ 4 = 3,601,353.25
If the quotient is a whole number, then 4 and 3,601,353.25 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 | 14,405,413 | |
| -1 | 14,405,413 |
If you did it right, you will end up with this table:
| 1 | 11 | 79 | 121 | 137 | 869 | 1,331 | 1,507 | 9,559 | 10,823 | 16,577 | 105,149 | 119,053 | 182,347 | 1,309,583 | 14,405,413 |
| -1 | -11 | -79 | -121 | -137 | -869 | -1,331 | -1,507 | -9,559 | -10,823 | -16,577 | -105,149 | -119,053 | -182,347 | -1,309,583 | -14,405,413 |
