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 30,225,503, 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 | 30,225,503 | |
| -1 | -30,225,503 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,225,503.
Example:
1 x 30,225,503 = 30,225,503
and
-1 x -30,225,503 = 30,225,503
Notice both answers equal 30,225,503
With that explanation out of the way, let's continue. Next, we take the number 30,225,503 and divide it by 2:
30,225,503 ÷ 2 = 15,112,751.5
If the quotient is a whole number, then 2 and 15,112,751.5 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 | 30,225,503 | |
| -1 | -30,225,503 |
Now, we try dividing 30,225,503 by 3:
30,225,503 ÷ 3 = 10,075,167.6667
If the quotient is a whole number, then 3 and 10,075,167.6667 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 | 30,225,503 | |
| -1 | -30,225,503 |
Let's try dividing by 4:
30,225,503 ÷ 4 = 7,556,375.75
If the quotient is a whole number, then 4 and 7,556,375.75 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 | 30,225,503 | |
| -1 | 30,225,503 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 49 | 77 | 343 | 539 | 3,773 | 8,011 | 56,077 | 88,121 | 392,539 | 616,847 | 2,747,773 | 4,317,929 | 30,225,503 |
| -1 | -7 | -11 | -49 | -77 | -343 | -539 | -3,773 | -8,011 | -56,077 | -88,121 | -392,539 | -616,847 | -2,747,773 | -4,317,929 | -30,225,503 |
