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 30,044,315, 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 | 30,044,315 | |
| -1 | -30,044,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,044,315.
Example:
1 x 30,044,315 = 30,044,315
and
-1 x -30,044,315 = 30,044,315
Notice both answers equal 30,044,315
With that explanation out of the way, let's continue. Next, we take the number 30,044,315 and divide it by 2:
30,044,315 ÷ 2 = 15,022,157.5
If the quotient is a whole number, then 2 and 15,022,157.5 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 | 30,044,315 | |
| -1 | -30,044,315 |
Now, we try dividing 30,044,315 by 3:
30,044,315 ÷ 3 = 10,014,771.6667
If the quotient is a whole number, then 3 and 10,014,771.6667 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 | 30,044,315 | |
| -1 | -30,044,315 |
Let's try dividing by 4:
30,044,315 ÷ 4 = 7,511,078.75
If the quotient is a whole number, then 4 and 7,511,078.75 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 | 30,044,315 | |
| -1 | 30,044,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 43 | 215 | 301 | 1,505 | 19,963 | 99,815 | 139,741 | 698,705 | 858,409 | 4,292,045 | 6,008,863 | 30,044,315 |
| -1 | -5 | -7 | -35 | -43 | -215 | -301 | -1,505 | -19,963 | -99,815 | -139,741 | -698,705 | -858,409 | -4,292,045 | -6,008,863 | -30,044,315 |
