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 16,807,583, 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 | 16,807,583 | |
| -1 | -16,807,583 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,807,583.
Example:
1 x 16,807,583 = 16,807,583
and
-1 x -16,807,583 = 16,807,583
Notice both answers equal 16,807,583
With that explanation out of the way, let's continue. Next, we take the number 16,807,583 and divide it by 2:
16,807,583 ÷ 2 = 8,403,791.5
If the quotient is a whole number, then 2 and 8,403,791.5 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 | 16,807,583 | |
| -1 | -16,807,583 |
Now, we try dividing 16,807,583 by 3:
16,807,583 ÷ 3 = 5,602,527.6667
If the quotient is a whole number, then 3 and 5,602,527.6667 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 | 16,807,583 | |
| -1 | -16,807,583 |
Let's try dividing by 4:
16,807,583 ÷ 4 = 4,201,895.75
If the quotient is a whole number, then 4 and 4,201,895.75 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 | 16,807,583 | |
| -1 | 16,807,583 |
If you did it right, you will end up with this table:
| 1 | 13 | 37 | 83 | 421 | 481 | 1,079 | 3,071 | 5,473 | 15,577 | 34,943 | 39,923 | 202,501 | 454,259 | 1,292,891 | 16,807,583 |
| -1 | -13 | -37 | -83 | -421 | -481 | -1,079 | -3,071 | -5,473 | -15,577 | -34,943 | -39,923 | -202,501 | -454,259 | -1,292,891 | -16,807,583 |
