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 30,467,213, 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 | 30,467,213 | |
| -1 | -30,467,213 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,467,213.
Example:
1 x 30,467,213 = 30,467,213
and
-1 x -30,467,213 = 30,467,213
Notice both answers equal 30,467,213
With that explanation out of the way, let's continue. Next, we take the number 30,467,213 and divide it by 2:
30,467,213 ÷ 2 = 15,233,606.5
If the quotient is a whole number, then 2 and 15,233,606.5 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 | 30,467,213 | |
| -1 | -30,467,213 |
Now, we try dividing 30,467,213 by 3:
30,467,213 ÷ 3 = 10,155,737.6667
If the quotient is a whole number, then 3 and 10,155,737.6667 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 | 30,467,213 | |
| -1 | -30,467,213 |
Let's try dividing by 4:
30,467,213 ÷ 4 = 7,616,803.25
If the quotient is a whole number, then 4 and 7,616,803.25 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 | 30,467,213 | |
| -1 | 30,467,213 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 503 | 509 | 3,521 | 3,563 | 8,551 | 8,653 | 59,857 | 60,571 | 256,027 | 1,792,189 | 4,352,459 | 30,467,213 |
| -1 | -7 | -17 | -119 | -503 | -509 | -3,521 | -3,563 | -8,551 | -8,653 | -59,857 | -60,571 | -256,027 | -1,792,189 | -4,352,459 | -30,467,213 |
