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 16,749,485, 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 | 16,749,485 | |
| -1 | -16,749,485 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,749,485.
Example:
1 x 16,749,485 = 16,749,485
and
-1 x -16,749,485 = 16,749,485
Notice both answers equal 16,749,485
With that explanation out of the way, let's continue. Next, we take the number 16,749,485 and divide it by 2:
16,749,485 ÷ 2 = 8,374,742.5
If the quotient is a whole number, then 2 and 8,374,742.5 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 | 16,749,485 | |
| -1 | -16,749,485 |
Now, we try dividing 16,749,485 by 3:
16,749,485 ÷ 3 = 5,583,161.6667
If the quotient is a whole number, then 3 and 5,583,161.6667 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 | 16,749,485 | |
| -1 | -16,749,485 |
Let's try dividing by 4:
16,749,485 ÷ 4 = 4,187,371.25
If the quotient is a whole number, then 4 and 4,187,371.25 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 | 16,749,485 | |
| -1 | 16,749,485 |
If you did it right, you will end up with this table:
| 1 | 5 | 73 | 109 | 365 | 421 | 545 | 2,105 | 7,957 | 30,733 | 39,785 | 45,889 | 153,665 | 229,445 | 3,349,897 | 16,749,485 |
| -1 | -5 | -73 | -109 | -365 | -421 | -545 | -2,105 | -7,957 | -30,733 | -39,785 | -45,889 | -153,665 | -229,445 | -3,349,897 | -16,749,485 |
