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 30,467,875, 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 | 30,467,875 | |
| -1 | -30,467,875 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,467,875.
Example:
1 x 30,467,875 = 30,467,875
and
-1 x -30,467,875 = 30,467,875
Notice both answers equal 30,467,875
With that explanation out of the way, let's continue. Next, we take the number 30,467,875 and divide it by 2:
30,467,875 ÷ 2 = 15,233,937.5
If the quotient is a whole number, then 2 and 15,233,937.5 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 | 30,467,875 | |
| -1 | -30,467,875 |
Now, we try dividing 30,467,875 by 3:
30,467,875 ÷ 3 = 10,155,958.3333
If the quotient is a whole number, then 3 and 10,155,958.3333 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 | 30,467,875 | |
| -1 | -30,467,875 |
Let's try dividing by 4:
30,467,875 ÷ 4 = 7,616,968.75
If the quotient is a whole number, then 4 and 7,616,968.75 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 | 30,467,875 | |
| -1 | 30,467,875 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 71 | 125 | 355 | 1,775 | 3,433 | 8,875 | 17,165 | 85,825 | 243,743 | 429,125 | 1,218,715 | 6,093,575 | 30,467,875 |
| -1 | -5 | -25 | -71 | -125 | -355 | -1,775 | -3,433 | -8,875 | -17,165 | -85,825 | -243,743 | -429,125 | -1,218,715 | -6,093,575 | -30,467,875 |
