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 16,683,947, 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 | 16,683,947 | |
| -1 | -16,683,947 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,683,947.
Example:
1 x 16,683,947 = 16,683,947
and
-1 x -16,683,947 = 16,683,947
Notice both answers equal 16,683,947
With that explanation out of the way, let's continue. Next, we take the number 16,683,947 and divide it by 2:
16,683,947 ÷ 2 = 8,341,973.5
If the quotient is a whole number, then 2 and 8,341,973.5 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 | 16,683,947 | |
| -1 | -16,683,947 |
Now, we try dividing 16,683,947 by 3:
16,683,947 ÷ 3 = 5,561,315.6667
If the quotient is a whole number, then 3 and 5,561,315.6667 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 | 16,683,947 | |
| -1 | -16,683,947 |
Let's try dividing by 4:
16,683,947 ÷ 4 = 4,170,986.75
If the quotient is a whole number, then 4 and 4,170,986.75 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 | 16,683,947 | |
| -1 | 16,683,947 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 161 | 173 | 599 | 1,211 | 3,979 | 4,193 | 13,777 | 27,853 | 96,439 | 103,627 | 725,389 | 2,383,421 | 16,683,947 |
| -1 | -7 | -23 | -161 | -173 | -599 | -1,211 | -3,979 | -4,193 | -13,777 | -27,853 | -96,439 | -103,627 | -725,389 | -2,383,421 | -16,683,947 |
