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 30,214,459, 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 | 30,214,459 | |
| -1 | -30,214,459 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,214,459.
Example:
1 x 30,214,459 = 30,214,459
and
-1 x -30,214,459 = 30,214,459
Notice both answers equal 30,214,459
With that explanation out of the way, let's continue. Next, we take the number 30,214,459 and divide it by 2:
30,214,459 ÷ 2 = 15,107,229.5
If the quotient is a whole number, then 2 and 15,107,229.5 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 | 30,214,459 | |
| -1 | -30,214,459 |
Now, we try dividing 30,214,459 by 3:
30,214,459 ÷ 3 = 10,071,486.3333
If the quotient is a whole number, then 3 and 10,071,486.3333 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 | 30,214,459 | |
| -1 | -30,214,459 |
Let's try dividing by 4:
30,214,459 ÷ 4 = 7,553,614.75
If the quotient is a whole number, then 4 and 7,553,614.75 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 | 30,214,459 | |
| -1 | 30,214,459 |
If you did it right, you will end up with this table:
| 1 | 11 | 37 | 61 | 407 | 671 | 1,217 | 2,257 | 13,387 | 24,827 | 45,029 | 74,237 | 495,319 | 816,607 | 2,746,769 | 30,214,459 |
| -1 | -11 | -37 | -61 | -407 | -671 | -1,217 | -2,257 | -13,387 | -24,827 | -45,029 | -74,237 | -495,319 | -816,607 | -2,746,769 | -30,214,459 |
