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 16,344,713, 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 | 16,344,713 | |
| -1 | -16,344,713 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,344,713.
Example:
1 x 16,344,713 = 16,344,713
and
-1 x -16,344,713 = 16,344,713
Notice both answers equal 16,344,713
With that explanation out of the way, let's continue. Next, we take the number 16,344,713 and divide it by 2:
16,344,713 ÷ 2 = 8,172,356.5
If the quotient is a whole number, then 2 and 8,172,356.5 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 | 16,344,713 | |
| -1 | -16,344,713 |
Now, we try dividing 16,344,713 by 3:
16,344,713 ÷ 3 = 5,448,237.6667
If the quotient is a whole number, then 3 and 5,448,237.6667 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 | 16,344,713 | |
| -1 | -16,344,713 |
Let's try dividing by 4:
16,344,713 ÷ 4 = 4,086,178.25
If the quotient is a whole number, then 4 and 4,086,178.25 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 | 16,344,713 | |
| -1 | 16,344,713 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 37 | 77 | 259 | 407 | 2,849 | 5,737 | 40,159 | 63,107 | 212,269 | 441,749 | 1,485,883 | 2,334,959 | 16,344,713 |
| -1 | -7 | -11 | -37 | -77 | -259 | -407 | -2,849 | -5,737 | -40,159 | -63,107 | -212,269 | -441,749 | -1,485,883 | -2,334,959 | -16,344,713 |
