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 16,803,085, 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 | 16,803,085 | |
| -1 | -16,803,085 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,803,085.
Example:
1 x 16,803,085 = 16,803,085
and
-1 x -16,803,085 = 16,803,085
Notice both answers equal 16,803,085
With that explanation out of the way, let's continue. Next, we take the number 16,803,085 and divide it by 2:
16,803,085 ÷ 2 = 8,401,542.5
If the quotient is a whole number, then 2 and 8,401,542.5 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 | 16,803,085 | |
| -1 | -16,803,085 |
Now, we try dividing 16,803,085 by 3:
16,803,085 ÷ 3 = 5,601,028.3333
If the quotient is a whole number, then 3 and 5,601,028.3333 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 | 16,803,085 | |
| -1 | -16,803,085 |
Let's try dividing by 4:
16,803,085 ÷ 4 = 4,200,771.25
If the quotient is a whole number, then 4 and 4,200,771.25 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 | 16,803,085 | |
| -1 | 16,803,085 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 31 | 65 | 155 | 269 | 403 | 961 | 1,345 | 2,015 | 3,497 | 4,805 | 8,339 | 12,493 | 17,485 | 41,695 | 62,465 | 108,407 | 258,509 | 542,035 | 1,292,545 | 3,360,617 | 16,803,085 |
| -1 | -5 | -13 | -31 | -65 | -155 | -269 | -403 | -961 | -1,345 | -2,015 | -3,497 | -4,805 | -8,339 | -12,493 | -17,485 | -41,695 | -62,465 | -108,407 | -258,509 | -542,035 | -1,292,545 | -3,360,617 | -16,803,085 |
