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 30,167,005, 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 | 30,167,005 | |
| -1 | -30,167,005 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,167,005.
Example:
1 x 30,167,005 = 30,167,005
and
-1 x -30,167,005 = 30,167,005
Notice both answers equal 30,167,005
With that explanation out of the way, let's continue. Next, we take the number 30,167,005 and divide it by 2:
30,167,005 ÷ 2 = 15,083,502.5
If the quotient is a whole number, then 2 and 15,083,502.5 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 | 30,167,005 | |
| -1 | -30,167,005 |
Now, we try dividing 30,167,005 by 3:
30,167,005 ÷ 3 = 10,055,668.3333
If the quotient is a whole number, then 3 and 10,055,668.3333 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 | 30,167,005 | |
| -1 | -30,167,005 |
Let's try dividing by 4:
30,167,005 ÷ 4 = 7,541,751.25
If the quotient is a whole number, then 4 and 7,541,751.25 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 | 30,167,005 | |
| -1 | 30,167,005 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 269 | 1,345 | 2,039 | 2,959 | 10,195 | 14,795 | 22,429 | 112,145 | 548,491 | 2,742,455 | 6,033,401 | 30,167,005 |
| -1 | -5 | -11 | -55 | -269 | -1,345 | -2,039 | -2,959 | -10,195 | -14,795 | -22,429 | -112,145 | -548,491 | -2,742,455 | -6,033,401 | -30,167,005 |
