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 8,990,033, 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 | 8,990,033 | |
| -1 | -8,990,033 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,990,033.
Example:
1 x 8,990,033 = 8,990,033
and
-1 x -8,990,033 = 8,990,033
Notice both answers equal 8,990,033
With that explanation out of the way, let's continue. Next, we take the number 8,990,033 and divide it by 2:
8,990,033 ÷ 2 = 4,495,016.5
If the quotient is a whole number, then 2 and 4,495,016.5 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 | 8,990,033 | |
| -1 | -8,990,033 |
Now, we try dividing 8,990,033 by 3:
8,990,033 ÷ 3 = 2,996,677.6667
If the quotient is a whole number, then 3 and 2,996,677.6667 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 | 8,990,033 | |
| -1 | -8,990,033 |
Let's try dividing by 4:
8,990,033 ÷ 4 = 2,247,508.25
If the quotient is a whole number, then 4 and 2,247,508.25 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 | 8,990,033 | |
| -1 | 8,990,033 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 107 | 281 | 299 | 1,391 | 2,461 | 3,653 | 6,463 | 30,067 | 31,993 | 84,019 | 390,871 | 691,541 | 8,990,033 |
| -1 | -13 | -23 | -107 | -281 | -299 | -1,391 | -2,461 | -3,653 | -6,463 | -30,067 | -31,993 | -84,019 | -390,871 | -691,541 | -8,990,033 |
