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 30,255,055, 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 | 30,255,055 | |
| -1 | -30,255,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,255,055.
Example:
1 x 30,255,055 = 30,255,055
and
-1 x -30,255,055 = 30,255,055
Notice both answers equal 30,255,055
With that explanation out of the way, let's continue. Next, we take the number 30,255,055 and divide it by 2:
30,255,055 ÷ 2 = 15,127,527.5
If the quotient is a whole number, then 2 and 15,127,527.5 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 | 30,255,055 | |
| -1 | -30,255,055 |
Now, we try dividing 30,255,055 by 3:
30,255,055 ÷ 3 = 10,085,018.3333
If the quotient is a whole number, then 3 and 10,085,018.3333 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 | 30,255,055 | |
| -1 | -30,255,055 |
Let's try dividing by 4:
30,255,055 ÷ 4 = 7,563,763.75
If the quotient is a whole number, then 4 and 7,563,763.75 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 | 30,255,055 | |
| -1 | 30,255,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 101 | 181 | 331 | 505 | 905 | 1,655 | 18,281 | 33,431 | 59,911 | 91,405 | 167,155 | 299,555 | 6,051,011 | 30,255,055 |
| -1 | -5 | -101 | -181 | -331 | -505 | -905 | -1,655 | -18,281 | -33,431 | -59,911 | -91,405 | -167,155 | -299,555 | -6,051,011 | -30,255,055 |
