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 30,253,303, 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 | 30,253,303 | |
| -1 | -30,253,303 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,253,303.
Example:
1 x 30,253,303 = 30,253,303
and
-1 x -30,253,303 = 30,253,303
Notice both answers equal 30,253,303
With that explanation out of the way, let's continue. Next, we take the number 30,253,303 and divide it by 2:
30,253,303 ÷ 2 = 15,126,651.5
If the quotient is a whole number, then 2 and 15,126,651.5 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 | 30,253,303 | |
| -1 | -30,253,303 |
Now, we try dividing 30,253,303 by 3:
30,253,303 ÷ 3 = 10,084,434.3333
If the quotient is a whole number, then 3 and 10,084,434.3333 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 | 30,253,303 | |
| -1 | -30,253,303 |
Let's try dividing by 4:
30,253,303 ÷ 4 = 7,563,325.75
If the quotient is a whole number, then 4 and 7,563,325.75 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 | 30,253,303 | |
| -1 | 30,253,303 |
If you did it right, you will end up with this table:
| 1 | 23 | 31 | 151 | 281 | 713 | 3,473 | 4,681 | 6,463 | 8,711 | 42,431 | 107,663 | 200,353 | 975,913 | 1,315,361 | 30,253,303 |
| -1 | -23 | -31 | -151 | -281 | -713 | -3,473 | -4,681 | -6,463 | -8,711 | -42,431 | -107,663 | -200,353 | -975,913 | -1,315,361 | -30,253,303 |
