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 16,456,565, 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 | 16,456,565 | |
| -1 | -16,456,565 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,456,565.
Example:
1 x 16,456,565 = 16,456,565
and
-1 x -16,456,565 = 16,456,565
Notice both answers equal 16,456,565
With that explanation out of the way, let's continue. Next, we take the number 16,456,565 and divide it by 2:
16,456,565 ÷ 2 = 8,228,282.5
If the quotient is a whole number, then 2 and 8,228,282.5 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 | 16,456,565 | |
| -1 | -16,456,565 |
Now, we try dividing 16,456,565 by 3:
16,456,565 ÷ 3 = 5,485,521.6667
If the quotient is a whole number, then 3 and 5,485,521.6667 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 | 16,456,565 | |
| -1 | -16,456,565 |
Let's try dividing by 4:
16,456,565 ÷ 4 = 4,114,141.25
If the quotient is a whole number, then 4 and 4,114,141.25 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 | 16,456,565 | |
| -1 | 16,456,565 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 311 | 557 | 1,555 | 2,785 | 5,909 | 10,583 | 29,545 | 52,915 | 173,227 | 866,135 | 3,291,313 | 16,456,565 |
| -1 | -5 | -19 | -95 | -311 | -557 | -1,555 | -2,785 | -5,909 | -10,583 | -29,545 | -52,915 | -173,227 | -866,135 | -3,291,313 | -16,456,565 |
