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 16,022,783, 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 | 16,022,783 | |
| -1 | -16,022,783 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,022,783.
Example:
1 x 16,022,783 = 16,022,783
and
-1 x -16,022,783 = 16,022,783
Notice both answers equal 16,022,783
With that explanation out of the way, let's continue. Next, we take the number 16,022,783 and divide it by 2:
16,022,783 ÷ 2 = 8,011,391.5
If the quotient is a whole number, then 2 and 8,011,391.5 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 | 16,022,783 | |
| -1 | -16,022,783 |
Now, we try dividing 16,022,783 by 3:
16,022,783 ÷ 3 = 5,340,927.6667
If the quotient is a whole number, then 3 and 5,340,927.6667 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 | 16,022,783 | |
| -1 | -16,022,783 |
Let's try dividing by 4:
16,022,783 ÷ 4 = 4,005,695.75
If the quotient is a whole number, then 4 and 4,005,695.75 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 | 16,022,783 | |
| -1 | 16,022,783 |
If you did it right, you will end up with this table:
| 1 | 7 | 71 | 103 | 313 | 497 | 721 | 2,191 | 7,313 | 22,223 | 32,239 | 51,191 | 155,561 | 225,673 | 2,288,969 | 16,022,783 |
| -1 | -7 | -71 | -103 | -313 | -497 | -721 | -2,191 | -7,313 | -22,223 | -32,239 | -51,191 | -155,561 | -225,673 | -2,288,969 | -16,022,783 |
