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 16,583,399, 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 | 16,583,399 | |
| -1 | -16,583,399 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,583,399.
Example:
1 x 16,583,399 = 16,583,399
and
-1 x -16,583,399 = 16,583,399
Notice both answers equal 16,583,399
With that explanation out of the way, let's continue. Next, we take the number 16,583,399 and divide it by 2:
16,583,399 ÷ 2 = 8,291,699.5
If the quotient is a whole number, then 2 and 8,291,699.5 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 | 16,583,399 | |
| -1 | -16,583,399 |
Now, we try dividing 16,583,399 by 3:
16,583,399 ÷ 3 = 5,527,799.6667
If the quotient is a whole number, then 3 and 5,527,799.6667 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 | 16,583,399 | |
| -1 | -16,583,399 |
Let's try dividing by 4:
16,583,399 ÷ 4 = 4,145,849.75
If the quotient is a whole number, then 4 and 4,145,849.75 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 | 16,583,399 | |
| -1 | 16,583,399 |
If you did it right, you will end up with this table:
| 1 | 7 | 61 | 71 | 427 | 497 | 547 | 3,829 | 4,331 | 30,317 | 33,367 | 38,837 | 233,569 | 271,859 | 2,369,057 | 16,583,399 |
| -1 | -7 | -61 | -71 | -427 | -497 | -547 | -3,829 | -4,331 | -30,317 | -33,367 | -38,837 | -233,569 | -271,859 | -2,369,057 | -16,583,399 |
