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 8,179,193, 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 | 8,179,193 | |
| -1 | -8,179,193 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,179,193.
Example:
1 x 8,179,193 = 8,179,193
and
-1 x -8,179,193 = 8,179,193
Notice both answers equal 8,179,193
With that explanation out of the way, let's continue. Next, we take the number 8,179,193 and divide it by 2:
8,179,193 ÷ 2 = 4,089,596.5
If the quotient is a whole number, then 2 and 4,089,596.5 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 | 8,179,193 | |
| -1 | -8,179,193 |
Now, we try dividing 8,179,193 by 3:
8,179,193 ÷ 3 = 2,726,397.6667
If the quotient is a whole number, then 3 and 2,726,397.6667 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 | 8,179,193 | |
| -1 | -8,179,193 |
Let's try dividing by 4:
8,179,193 ÷ 4 = 2,044,798.25
If the quotient is a whole number, then 4 and 2,044,798.25 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 | 8,179,193 | |
| -1 | 8,179,193 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 187 | 191 | 229 | 2,101 | 2,519 | 3,247 | 3,893 | 35,717 | 42,823 | 43,739 | 481,129 | 743,563 | 8,179,193 |
| -1 | -11 | -17 | -187 | -191 | -229 | -2,101 | -2,519 | -3,247 | -3,893 | -35,717 | -42,823 | -43,739 | -481,129 | -743,563 | -8,179,193 |
