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 30,225,635, 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 | 30,225,635 | |
| -1 | -30,225,635 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,225,635.
Example:
1 x 30,225,635 = 30,225,635
and
-1 x -30,225,635 = 30,225,635
Notice both answers equal 30,225,635
With that explanation out of the way, let's continue. Next, we take the number 30,225,635 and divide it by 2:
30,225,635 ÷ 2 = 15,112,817.5
If the quotient is a whole number, then 2 and 15,112,817.5 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 | 30,225,635 | |
| -1 | -30,225,635 |
Now, we try dividing 30,225,635 by 3:
30,225,635 ÷ 3 = 10,075,211.6667
If the quotient is a whole number, then 3 and 10,075,211.6667 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 | 30,225,635 | |
| -1 | -30,225,635 |
Let's try dividing by 4:
30,225,635 ÷ 4 = 7,556,408.75
If the quotient is a whole number, then 4 and 7,556,408.75 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 | 30,225,635 | |
| -1 | 30,225,635 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 53 | 55 | 265 | 583 | 2,915 | 10,369 | 51,845 | 114,059 | 549,557 | 570,295 | 2,747,785 | 6,045,127 | 30,225,635 |
| -1 | -5 | -11 | -53 | -55 | -265 | -583 | -2,915 | -10,369 | -51,845 | -114,059 | -549,557 | -570,295 | -2,747,785 | -6,045,127 | -30,225,635 |
