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 8,044,745, 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 | 8,044,745 | |
| -1 | -8,044,745 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,044,745.
Example:
1 x 8,044,745 = 8,044,745
and
-1 x -8,044,745 = 8,044,745
Notice both answers equal 8,044,745
With that explanation out of the way, let's continue. Next, we take the number 8,044,745 and divide it by 2:
8,044,745 ÷ 2 = 4,022,372.5
If the quotient is a whole number, then 2 and 4,022,372.5 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 | 8,044,745 | |
| -1 | -8,044,745 |
Now, we try dividing 8,044,745 by 3:
8,044,745 ÷ 3 = 2,681,581.6667
If the quotient is a whole number, then 3 and 2,681,581.6667 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 | 8,044,745 | |
| -1 | -8,044,745 |
Let's try dividing by 4:
8,044,745 ÷ 4 = 2,011,186.25
If the quotient is a whole number, then 4 and 2,011,186.25 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 | 8,044,745 | |
| -1 | 8,044,745 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 109 | 145 | 509 | 545 | 2,545 | 3,161 | 14,761 | 15,805 | 55,481 | 73,805 | 277,405 | 1,608,949 | 8,044,745 |
| -1 | -5 | -29 | -109 | -145 | -509 | -545 | -2,545 | -3,161 | -14,761 | -15,805 | -55,481 | -73,805 | -277,405 | -1,608,949 | -8,044,745 |
