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 8,033,389, 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 | 8,033,389 | |
| -1 | -8,033,389 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,033,389.
Example:
1 x 8,033,389 = 8,033,389
and
-1 x -8,033,389 = 8,033,389
Notice both answers equal 8,033,389
With that explanation out of the way, let's continue. Next, we take the number 8,033,389 and divide it by 2:
8,033,389 ÷ 2 = 4,016,694.5
If the quotient is a whole number, then 2 and 4,016,694.5 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 | 8,033,389 | |
| -1 | -8,033,389 |
Now, we try dividing 8,033,389 by 3:
8,033,389 ÷ 3 = 2,677,796.3333
If the quotient is a whole number, then 3 and 2,677,796.3333 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 | 8,033,389 | |
| -1 | -8,033,389 |
Let's try dividing by 4:
8,033,389 ÷ 4 = 2,008,347.25
If the quotient is a whole number, then 4 and 2,008,347.25 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 | 8,033,389 | |
| -1 | 8,033,389 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 43 | 91 | 301 | 559 | 2,053 | 3,913 | 14,371 | 26,689 | 88,279 | 186,823 | 617,953 | 1,147,627 | 8,033,389 |
| -1 | -7 | -13 | -43 | -91 | -301 | -559 | -2,053 | -3,913 | -14,371 | -26,689 | -88,279 | -186,823 | -617,953 | -1,147,627 | -8,033,389 |
