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 16,088,605, 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 | 16,088,605 | |
| -1 | -16,088,605 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,088,605.
Example:
1 x 16,088,605 = 16,088,605
and
-1 x -16,088,605 = 16,088,605
Notice both answers equal 16,088,605
With that explanation out of the way, let's continue. Next, we take the number 16,088,605 and divide it by 2:
16,088,605 ÷ 2 = 8,044,302.5
If the quotient is a whole number, then 2 and 8,044,302.5 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 | 16,088,605 | |
| -1 | -16,088,605 |
Now, we try dividing 16,088,605 by 3:
16,088,605 ÷ 3 = 5,362,868.3333
If the quotient is a whole number, then 3 and 5,362,868.3333 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 | 16,088,605 | |
| -1 | -16,088,605 |
Let's try dividing by 4:
16,088,605 ÷ 4 = 4,022,151.25
If the quotient is a whole number, then 4 and 4,022,151.25 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 | 16,088,605 | |
| -1 | 16,088,605 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 41 | 65 | 205 | 533 | 2,665 | 6,037 | 30,185 | 78,481 | 247,517 | 392,405 | 1,237,585 | 3,217,721 | 16,088,605 |
| -1 | -5 | -13 | -41 | -65 | -205 | -533 | -2,665 | -6,037 | -30,185 | -78,481 | -247,517 | -392,405 | -1,237,585 | -3,217,721 | -16,088,605 |
