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 30,253,301, 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 | 30,253,301 | |
| -1 | -30,253,301 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,253,301.
Example:
1 x 30,253,301 = 30,253,301
and
-1 x -30,253,301 = 30,253,301
Notice both answers equal 30,253,301
With that explanation out of the way, let's continue. Next, we take the number 30,253,301 and divide it by 2:
30,253,301 ÷ 2 = 15,126,650.5
If the quotient is a whole number, then 2 and 15,126,650.5 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 | 30,253,301 | |
| -1 | -30,253,301 |
Now, we try dividing 30,253,301 by 3:
30,253,301 ÷ 3 = 10,084,433.6667
If the quotient is a whole number, then 3 and 10,084,433.6667 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 | 30,253,301 | |
| -1 | -30,253,301 |
Let's try dividing by 4:
30,253,301 ÷ 4 = 7,563,325.25
If the quotient is a whole number, then 4 and 7,563,325.25 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 | 30,253,301 | |
| -1 | 30,253,301 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 53 | 247 | 689 | 1,007 | 2,311 | 13,091 | 30,043 | 43,909 | 122,483 | 570,817 | 1,592,279 | 2,327,177 | 30,253,301 |
| -1 | -13 | -19 | -53 | -247 | -689 | -1,007 | -2,311 | -13,091 | -30,043 | -43,909 | -122,483 | -570,817 | -1,592,279 | -2,327,177 | -30,253,301 |
