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 30,036,413, 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 | 30,036,413 | |
| -1 | -30,036,413 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,036,413.
Example:
1 x 30,036,413 = 30,036,413
and
-1 x -30,036,413 = 30,036,413
Notice both answers equal 30,036,413
With that explanation out of the way, let's continue. Next, we take the number 30,036,413 and divide it by 2:
30,036,413 ÷ 2 = 15,018,206.5
If the quotient is a whole number, then 2 and 15,018,206.5 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 | 30,036,413 | |
| -1 | -30,036,413 |
Now, we try dividing 30,036,413 by 3:
30,036,413 ÷ 3 = 10,012,137.6667
If the quotient is a whole number, then 3 and 10,012,137.6667 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 | 30,036,413 | |
| -1 | -30,036,413 |
Let's try dividing by 4:
30,036,413 ÷ 4 = 7,509,103.25
If the quotient is a whole number, then 4 and 7,509,103.25 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 | 30,036,413 | |
| -1 | 30,036,413 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 227 | 253 | 523 | 2,497 | 5,221 | 5,753 | 12,029 | 57,431 | 118,721 | 132,319 | 1,305,931 | 2,730,583 | 30,036,413 |
| -1 | -11 | -23 | -227 | -253 | -523 | -2,497 | -5,221 | -5,753 | -12,029 | -57,431 | -118,721 | -132,319 | -1,305,931 | -2,730,583 | -30,036,413 |
