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 30,594,665, 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 | 30,594,665 | |
| -1 | -30,594,665 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,594,665.
Example:
1 x 30,594,665 = 30,594,665
and
-1 x -30,594,665 = 30,594,665
Notice both answers equal 30,594,665
With that explanation out of the way, let's continue. Next, we take the number 30,594,665 and divide it by 2:
30,594,665 ÷ 2 = 15,297,332.5
If the quotient is a whole number, then 2 and 15,297,332.5 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 | 30,594,665 | |
| -1 | -30,594,665 |
Now, we try dividing 30,594,665 by 3:
30,594,665 ÷ 3 = 10,198,221.6667
If the quotient is a whole number, then 3 and 10,198,221.6667 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 | 30,594,665 | |
| -1 | -30,594,665 |
Let's try dividing by 4:
30,594,665 ÷ 4 = 7,648,666.25
If the quotient is a whole number, then 4 and 7,648,666.25 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 | 30,594,665 | |
| -1 | 30,594,665 |
If you did it right, you will end up with this table:
| 1 | 5 | 73 | 109 | 365 | 545 | 769 | 3,845 | 7,957 | 39,785 | 56,137 | 83,821 | 280,685 | 419,105 | 6,118,933 | 30,594,665 |
| -1 | -5 | -73 | -109 | -365 | -545 | -769 | -3,845 | -7,957 | -39,785 | -56,137 | -83,821 | -280,685 | -419,105 | -6,118,933 | -30,594,665 |
