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 30,504,575, 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 | 30,504,575 | |
| -1 | -30,504,575 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,504,575.
Example:
1 x 30,504,575 = 30,504,575
and
-1 x -30,504,575 = 30,504,575
Notice both answers equal 30,504,575
With that explanation out of the way, let's continue. Next, we take the number 30,504,575 and divide it by 2:
30,504,575 ÷ 2 = 15,252,287.5
If the quotient is a whole number, then 2 and 15,252,287.5 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 | 30,504,575 | |
| -1 | -30,504,575 |
Now, we try dividing 30,504,575 by 3:
30,504,575 ÷ 3 = 10,168,191.6667
If the quotient is a whole number, then 3 and 10,168,191.6667 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 | 30,504,575 | |
| -1 | -30,504,575 |
Let's try dividing by 4:
30,504,575 ÷ 4 = 7,626,143.75
If the quotient is a whole number, then 4 and 7,626,143.75 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 | 30,504,575 | |
| -1 | 30,504,575 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 61 | 83 | 241 | 305 | 415 | 1,205 | 1,525 | 2,075 | 5,063 | 6,025 | 14,701 | 20,003 | 25,315 | 73,505 | 100,015 | 126,575 | 367,525 | 500,075 | 1,220,183 | 6,100,915 | 30,504,575 |
| -1 | -5 | -25 | -61 | -83 | -241 | -305 | -415 | -1,205 | -1,525 | -2,075 | -5,063 | -6,025 | -14,701 | -20,003 | -25,315 | -73,505 | -100,015 | -126,575 | -367,525 | -500,075 | -1,220,183 | -6,100,915 | -30,504,575 |
