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 30,433,645, 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 | 30,433,645 | |
| -1 | -30,433,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,433,645.
Example:
1 x 30,433,645 = 30,433,645
and
-1 x -30,433,645 = 30,433,645
Notice both answers equal 30,433,645
With that explanation out of the way, let's continue. Next, we take the number 30,433,645 and divide it by 2:
30,433,645 ÷ 2 = 15,216,822.5
If the quotient is a whole number, then 2 and 15,216,822.5 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 | 30,433,645 | |
| -1 | -30,433,645 |
Now, we try dividing 30,433,645 by 3:
30,433,645 ÷ 3 = 10,144,548.3333
If the quotient is a whole number, then 3 and 10,144,548.3333 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 | 30,433,645 | |
| -1 | -30,433,645 |
Let's try dividing by 4:
30,433,645 ÷ 4 = 7,608,411.25
If the quotient is a whole number, then 4 and 7,608,411.25 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 | 30,433,645 | |
| -1 | 30,433,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 127 | 635 | 1,397 | 4,357 | 6,985 | 21,785 | 47,927 | 239,635 | 553,339 | 2,766,695 | 6,086,729 | 30,433,645 |
| -1 | -5 | -11 | -55 | -127 | -635 | -1,397 | -4,357 | -6,985 | -21,785 | -47,927 | -239,635 | -553,339 | -2,766,695 | -6,086,729 | -30,433,645 |
