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 16,646,575, 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 | 16,646,575 | |
| -1 | -16,646,575 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,646,575.
Example:
1 x 16,646,575 = 16,646,575
and
-1 x -16,646,575 = 16,646,575
Notice both answers equal 16,646,575
With that explanation out of the way, let's continue. Next, we take the number 16,646,575 and divide it by 2:
16,646,575 ÷ 2 = 8,323,287.5
If the quotient is a whole number, then 2 and 8,323,287.5 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 | 16,646,575 | |
| -1 | -16,646,575 |
Now, we try dividing 16,646,575 by 3:
16,646,575 ÷ 3 = 5,548,858.3333
If the quotient is a whole number, then 3 and 5,548,858.3333 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 | 16,646,575 | |
| -1 | -16,646,575 |
Let's try dividing by 4:
16,646,575 ÷ 4 = 4,161,643.75
If the quotient is a whole number, then 4 and 4,161,643.75 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 | 16,646,575 | |
| -1 | 16,646,575 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 121 | 275 | 605 | 3,025 | 5,503 | 27,515 | 60,533 | 137,575 | 302,665 | 665,863 | 1,513,325 | 3,329,315 | 16,646,575 |
| -1 | -5 | -11 | -25 | -55 | -121 | -275 | -605 | -3,025 | -5,503 | -27,515 | -60,533 | -137,575 | -302,665 | -665,863 | -1,513,325 | -3,329,315 | -16,646,575 |
