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 30,353,375, 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 | 30,353,375 | |
| -1 | -30,353,375 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,353,375.
Example:
1 x 30,353,375 = 30,353,375
and
-1 x -30,353,375 = 30,353,375
Notice both answers equal 30,353,375
With that explanation out of the way, let's continue. Next, we take the number 30,353,375 and divide it by 2:
30,353,375 ÷ 2 = 15,176,687.5
If the quotient is a whole number, then 2 and 15,176,687.5 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 | 30,353,375 | |
| -1 | -30,353,375 |
Now, we try dividing 30,353,375 by 3:
30,353,375 ÷ 3 = 10,117,791.6667
If the quotient is a whole number, then 3 and 10,117,791.6667 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 | 30,353,375 | |
| -1 | -30,353,375 |
Let's try dividing by 4:
30,353,375 ÷ 4 = 7,588,343.75
If the quotient is a whole number, then 4 and 7,588,343.75 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 | 30,353,375 | |
| -1 | 30,353,375 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 65 | 125 | 325 | 1,625 | 18,679 | 93,395 | 242,827 | 466,975 | 1,214,135 | 2,334,875 | 6,070,675 | 30,353,375 |
| -1 | -5 | -13 | -25 | -65 | -125 | -325 | -1,625 | -18,679 | -93,395 | -242,827 | -466,975 | -1,214,135 | -2,334,875 | -6,070,675 | -30,353,375 |
