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 16,716,293, 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 | 16,716,293 | |
| -1 | -16,716,293 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,716,293.
Example:
1 x 16,716,293 = 16,716,293
and
-1 x -16,716,293 = 16,716,293
Notice both answers equal 16,716,293
With that explanation out of the way, let's continue. Next, we take the number 16,716,293 and divide it by 2:
16,716,293 ÷ 2 = 8,358,146.5
If the quotient is a whole number, then 2 and 8,358,146.5 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 | 16,716,293 | |
| -1 | -16,716,293 |
Now, we try dividing 16,716,293 by 3:
16,716,293 ÷ 3 = 5,572,097.6667
If the quotient is a whole number, then 3 and 5,572,097.6667 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 | 16,716,293 | |
| -1 | -16,716,293 |
Let's try dividing by 4:
16,716,293 ÷ 4 = 4,179,073.25
If the quotient is a whole number, then 4 and 4,179,073.25 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 | 16,716,293 | |
| -1 | 16,716,293 |
If you did it right, you will end up with this table:
| 1 | 11 | 43 | 59 | 473 | 599 | 649 | 2,537 | 6,589 | 25,757 | 27,907 | 35,341 | 283,327 | 388,751 | 1,519,663 | 16,716,293 |
| -1 | -11 | -43 | -59 | -473 | -599 | -649 | -2,537 | -6,589 | -25,757 | -27,907 | -35,341 | -283,327 | -388,751 | -1,519,663 | -16,716,293 |
