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 20,044,115, 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 | 20,044,115 | |
| -1 | -20,044,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 20,044,115.
Example:
1 x 20,044,115 = 20,044,115
and
-1 x -20,044,115 = 20,044,115
Notice both answers equal 20,044,115
With that explanation out of the way, let's continue. Next, we take the number 20,044,115 and divide it by 2:
20,044,115 ÷ 2 = 10,022,057.5
If the quotient is a whole number, then 2 and 10,022,057.5 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 | 20,044,115 | |
| -1 | -20,044,115 |
Now, we try dividing 20,044,115 by 3:
20,044,115 ÷ 3 = 6,681,371.6667
If the quotient is a whole number, then 3 and 6,681,371.6667 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 | 20,044,115 | |
| -1 | -20,044,115 |
Let's try dividing by 4:
20,044,115 ÷ 4 = 5,011,028.75
If the quotient is a whole number, then 4 and 5,011,028.75 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 | 20,044,115 | |
| -1 | 20,044,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 65 | 91 | 455 | 44,053 | 220,265 | 308,371 | 572,689 | 1,541,855 | 2,863,445 | 4,008,823 | 20,044,115 |
| -1 | -5 | -7 | -13 | -35 | -65 | -91 | -455 | -44,053 | -220,265 | -308,371 | -572,689 | -1,541,855 | -2,863,445 | -4,008,823 | -20,044,115 |
