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 30,467,605, 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 | 30,467,605 | |
| -1 | -30,467,605 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,467,605.
Example:
1 x 30,467,605 = 30,467,605
and
-1 x -30,467,605 = 30,467,605
Notice both answers equal 30,467,605
With that explanation out of the way, let's continue. Next, we take the number 30,467,605 and divide it by 2:
30,467,605 ÷ 2 = 15,233,802.5
If the quotient is a whole number, then 2 and 15,233,802.5 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 | 30,467,605 | |
| -1 | -30,467,605 |
Now, we try dividing 30,467,605 by 3:
30,467,605 ÷ 3 = 10,155,868.3333
If the quotient is a whole number, then 3 and 10,155,868.3333 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 | 30,467,605 | |
| -1 | -30,467,605 |
Let's try dividing by 4:
30,467,605 ÷ 4 = 7,616,901.25
If the quotient is a whole number, then 4 and 7,616,901.25 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 | 30,467,605 | |
| -1 | 30,467,605 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 293 | 1,465 | 2,051 | 2,971 | 10,255 | 14,855 | 20,797 | 103,985 | 870,503 | 4,352,515 | 6,093,521 | 30,467,605 |
| -1 | -5 | -7 | -35 | -293 | -1,465 | -2,051 | -2,971 | -10,255 | -14,855 | -20,797 | -103,985 | -870,503 | -4,352,515 | -6,093,521 | -30,467,605 |
