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 16,765,049, 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 | 16,765,049 | |
| -1 | -16,765,049 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,765,049.
Example:
1 x 16,765,049 = 16,765,049
and
-1 x -16,765,049 = 16,765,049
Notice both answers equal 16,765,049
With that explanation out of the way, let's continue. Next, we take the number 16,765,049 and divide it by 2:
16,765,049 ÷ 2 = 8,382,524.5
If the quotient is a whole number, then 2 and 8,382,524.5 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 | 16,765,049 | |
| -1 | -16,765,049 |
Now, we try dividing 16,765,049 by 3:
16,765,049 ÷ 3 = 5,588,349.6667
If the quotient is a whole number, then 3 and 5,588,349.6667 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 | 16,765,049 | |
| -1 | -16,765,049 |
Let's try dividing by 4:
16,765,049 ÷ 4 = 4,191,262.25
If the quotient is a whole number, then 4 and 4,191,262.25 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 | 16,765,049 | |
| -1 | 16,765,049 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 133 | 233 | 541 | 1,631 | 3,787 | 4,427 | 10,279 | 30,989 | 71,953 | 126,053 | 882,371 | 2,395,007 | 16,765,049 |
| -1 | -7 | -19 | -133 | -233 | -541 | -1,631 | -3,787 | -4,427 | -10,279 | -30,989 | -71,953 | -126,053 | -882,371 | -2,395,007 | -16,765,049 |
