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 16,807,739, 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 | 16,807,739 | |
| -1 | -16,807,739 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,807,739.
Example:
1 x 16,807,739 = 16,807,739
and
-1 x -16,807,739 = 16,807,739
Notice both answers equal 16,807,739
With that explanation out of the way, let's continue. Next, we take the number 16,807,739 and divide it by 2:
16,807,739 ÷ 2 = 8,403,869.5
If the quotient is a whole number, then 2 and 8,403,869.5 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 | 16,807,739 | |
| -1 | -16,807,739 |
Now, we try dividing 16,807,739 by 3:
16,807,739 ÷ 3 = 5,602,579.6667
If the quotient is a whole number, then 3 and 5,602,579.6667 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 | 16,807,739 | |
| -1 | -16,807,739 |
Let's try dividing by 4:
16,807,739 ÷ 4 = 4,201,934.75
If the quotient is a whole number, then 4 and 4,201,934.75 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 | 16,807,739 | |
| -1 | 16,807,739 |
If you did it right, you will end up with this table:
| 1 | 13 | 73 | 89 | 199 | 949 | 1,157 | 2,587 | 6,497 | 14,527 | 17,711 | 84,461 | 188,851 | 230,243 | 1,292,903 | 16,807,739 |
| -1 | -13 | -73 | -89 | -199 | -949 | -1,157 | -2,587 | -6,497 | -14,527 | -17,711 | -84,461 | -188,851 | -230,243 | -1,292,903 | -16,807,739 |
