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 30,344,455, 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 | 30,344,455 | |
| -1 | -30,344,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,344,455.
Example:
1 x 30,344,455 = 30,344,455
and
-1 x -30,344,455 = 30,344,455
Notice both answers equal 30,344,455
With that explanation out of the way, let's continue. Next, we take the number 30,344,455 and divide it by 2:
30,344,455 ÷ 2 = 15,172,227.5
If the quotient is a whole number, then 2 and 15,172,227.5 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 | 30,344,455 | |
| -1 | -30,344,455 |
Now, we try dividing 30,344,455 by 3:
30,344,455 ÷ 3 = 10,114,818.3333
If the quotient is a whole number, then 3 and 10,114,818.3333 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 | 30,344,455 | |
| -1 | -30,344,455 |
Let's try dividing by 4:
30,344,455 ÷ 4 = 7,586,113.75
If the quotient is a whole number, then 4 and 7,586,113.75 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 | 30,344,455 | |
| -1 | 30,344,455 |
If you did it right, you will end up with this table:
| 1 | 5 | 43 | 113 | 215 | 565 | 1,249 | 4,859 | 6,245 | 24,295 | 53,707 | 141,137 | 268,535 | 705,685 | 6,068,891 | 30,344,455 |
| -1 | -5 | -43 | -113 | -215 | -565 | -1,249 | -4,859 | -6,245 | -24,295 | -53,707 | -141,137 | -268,535 | -705,685 | -6,068,891 | -30,344,455 |
