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 8,120,593, 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 | 8,120,593 | |
| -1 | -8,120,593 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,120,593.
Example:
1 x 8,120,593 = 8,120,593
and
-1 x -8,120,593 = 8,120,593
Notice both answers equal 8,120,593
With that explanation out of the way, let's continue. Next, we take the number 8,120,593 and divide it by 2:
8,120,593 ÷ 2 = 4,060,296.5
If the quotient is a whole number, then 2 and 4,060,296.5 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 | 8,120,593 | |
| -1 | -8,120,593 |
Now, we try dividing 8,120,593 by 3:
8,120,593 ÷ 3 = 2,706,864.3333
If the quotient is a whole number, then 3 and 2,706,864.3333 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 | 8,120,593 | |
| -1 | -8,120,593 |
Let's try dividing by 4:
8,120,593 ÷ 4 = 2,030,148.25
If the quotient is a whole number, then 4 and 2,030,148.25 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 | 8,120,593 | |
| -1 | 8,120,593 |
If you did it right, you will end up with this table:
| 1 | 13 | 43 | 73 | 199 | 559 | 949 | 2,587 | 3,139 | 8,557 | 14,527 | 40,807 | 111,241 | 188,851 | 624,661 | 8,120,593 |
| -1 | -13 | -43 | -73 | -199 | -559 | -949 | -2,587 | -3,139 | -8,557 | -14,527 | -40,807 | -111,241 | -188,851 | -624,661 | -8,120,593 |
