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 16,352,287, 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 | 16,352,287 | |
| -1 | -16,352,287 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,352,287.
Example:
1 x 16,352,287 = 16,352,287
and
-1 x -16,352,287 = 16,352,287
Notice both answers equal 16,352,287
With that explanation out of the way, let's continue. Next, we take the number 16,352,287 and divide it by 2:
16,352,287 ÷ 2 = 8,176,143.5
If the quotient is a whole number, then 2 and 8,176,143.5 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 | 16,352,287 | |
| -1 | -16,352,287 |
Now, we try dividing 16,352,287 by 3:
16,352,287 ÷ 3 = 5,450,762.3333
If the quotient is a whole number, then 3 and 5,450,762.3333 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 | 16,352,287 | |
| -1 | -16,352,287 |
Let's try dividing by 4:
16,352,287 ÷ 4 = 4,088,071.75
If the quotient is a whole number, then 4 and 4,088,071.75 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 | 16,352,287 | |
| -1 | 16,352,287 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 47 | 161 | 329 | 1,081 | 2,161 | 7,567 | 15,127 | 49,703 | 101,567 | 347,921 | 710,969 | 2,336,041 | 16,352,287 |
| -1 | -7 | -23 | -47 | -161 | -329 | -1,081 | -2,161 | -7,567 | -15,127 | -49,703 | -101,567 | -347,921 | -710,969 | -2,336,041 | -16,352,287 |
