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 30,002,089, 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 | 30,002,089 | |
| -1 | -30,002,089 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,002,089.
Example:
1 x 30,002,089 = 30,002,089
and
-1 x -30,002,089 = 30,002,089
Notice both answers equal 30,002,089
With that explanation out of the way, let's continue. Next, we take the number 30,002,089 and divide it by 2:
30,002,089 ÷ 2 = 15,001,044.5
If the quotient is a whole number, then 2 and 15,001,044.5 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 | 30,002,089 | |
| -1 | -30,002,089 |
Now, we try dividing 30,002,089 by 3:
30,002,089 ÷ 3 = 10,000,696.3333
If the quotient is a whole number, then 3 and 10,000,696.3333 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 | 30,002,089 | |
| -1 | -30,002,089 |
Let's try dividing by 4:
30,002,089 ÷ 4 = 7,500,522.25
If the quotient is a whole number, then 4 and 7,500,522.25 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 | 30,002,089 | |
| -1 | 30,002,089 |
If you did it right, you will end up with this table:
| 1 | 13 | 43 | 191 | 281 | 559 | 2,483 | 3,653 | 8,213 | 12,083 | 53,671 | 106,769 | 157,079 | 697,723 | 2,307,853 | 30,002,089 |
| -1 | -13 | -43 | -191 | -281 | -559 | -2,483 | -3,653 | -8,213 | -12,083 | -53,671 | -106,769 | -157,079 | -697,723 | -2,307,853 | -30,002,089 |
