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 30,030,655, 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 | 30,030,655 | |
| -1 | -30,030,655 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,030,655.
Example:
1 x 30,030,655 = 30,030,655
and
-1 x -30,030,655 = 30,030,655
Notice both answers equal 30,030,655
With that explanation out of the way, let's continue. Next, we take the number 30,030,655 and divide it by 2:
30,030,655 ÷ 2 = 15,015,327.5
If the quotient is a whole number, then 2 and 15,015,327.5 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 | 30,030,655 | |
| -1 | -30,030,655 |
Now, we try dividing 30,030,655 by 3:
30,030,655 ÷ 3 = 10,010,218.3333
If the quotient is a whole number, then 3 and 10,010,218.3333 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 | 30,030,655 | |
| -1 | -30,030,655 |
Let's try dividing by 4:
30,030,655 ÷ 4 = 7,507,663.75
If the quotient is a whole number, then 4 and 7,507,663.75 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 | 30,030,655 | |
| -1 | 30,030,655 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 205 | 263 | 557 | 1,315 | 2,785 | 10,783 | 22,837 | 53,915 | 114,185 | 146,491 | 732,455 | 6,006,131 | 30,030,655 |
| -1 | -5 | -41 | -205 | -263 | -557 | -1,315 | -2,785 | -10,783 | -22,837 | -53,915 | -114,185 | -146,491 | -732,455 | -6,006,131 | -30,030,655 |
