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 16,044,505, 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 | 16,044,505 | |
| -1 | -16,044,505 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,044,505.
Example:
1 x 16,044,505 = 16,044,505
and
-1 x -16,044,505 = 16,044,505
Notice both answers equal 16,044,505
With that explanation out of the way, let's continue. Next, we take the number 16,044,505 and divide it by 2:
16,044,505 ÷ 2 = 8,022,252.5
If the quotient is a whole number, then 2 and 8,022,252.5 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 | 16,044,505 | |
| -1 | -16,044,505 |
Now, we try dividing 16,044,505 by 3:
16,044,505 ÷ 3 = 5,348,168.3333
If the quotient is a whole number, then 3 and 5,348,168.3333 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 | 16,044,505 | |
| -1 | -16,044,505 |
Let's try dividing by 4:
16,044,505 ÷ 4 = 4,011,126.25
If the quotient is a whole number, then 4 and 4,011,126.25 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 | 16,044,505 | |
| -1 | 16,044,505 |
If you did it right, you will end up with this table:
| 1 | 5 | 79 | 151 | 269 | 395 | 755 | 1,345 | 11,929 | 21,251 | 40,619 | 59,645 | 106,255 | 203,095 | 3,208,901 | 16,044,505 |
| -1 | -5 | -79 | -151 | -269 | -395 | -755 | -1,345 | -11,929 | -21,251 | -40,619 | -59,645 | -106,255 | -203,095 | -3,208,901 | -16,044,505 |
