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 30,301,355, 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 | 30,301,355 | |
| -1 | -30,301,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,301,355.
Example:
1 x 30,301,355 = 30,301,355
and
-1 x -30,301,355 = 30,301,355
Notice both answers equal 30,301,355
With that explanation out of the way, let's continue. Next, we take the number 30,301,355 and divide it by 2:
30,301,355 ÷ 2 = 15,150,677.5
If the quotient is a whole number, then 2 and 15,150,677.5 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 | 30,301,355 | |
| -1 | -30,301,355 |
Now, we try dividing 30,301,355 by 3:
30,301,355 ÷ 3 = 10,100,451.6667
If the quotient is a whole number, then 3 and 10,100,451.6667 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 | 30,301,355 | |
| -1 | -30,301,355 |
Let's try dividing by 4:
30,301,355 ÷ 4 = 7,575,338.75
If the quotient is a whole number, then 4 and 7,575,338.75 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 | 30,301,355 | |
| -1 | 30,301,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 245 | 337 | 367 | 1,685 | 1,835 | 2,359 | 2,569 | 11,795 | 12,845 | 16,513 | 17,983 | 82,565 | 89,915 | 123,679 | 618,395 | 865,753 | 4,328,765 | 6,060,271 | 30,301,355 |
| -1 | -5 | -7 | -35 | -49 | -245 | -337 | -367 | -1,685 | -1,835 | -2,359 | -2,569 | -11,795 | -12,845 | -16,513 | -17,983 | -82,565 | -89,915 | -123,679 | -618,395 | -865,753 | -4,328,765 | -6,060,271 | -30,301,355 |
