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 33,481,477, 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 | 33,481,477 | |
| -1 | -33,481,477 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,481,477.
Example:
1 x 33,481,477 = 33,481,477
and
-1 x -33,481,477 = 33,481,477
Notice both answers equal 33,481,477
With that explanation out of the way, let's continue. Next, we take the number 33,481,477 and divide it by 2:
33,481,477 ÷ 2 = 16,740,738.5
If the quotient is a whole number, then 2 and 16,740,738.5 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 | 33,481,477 | |
| -1 | -33,481,477 |
Now, we try dividing 33,481,477 by 3:
33,481,477 ÷ 3 = 11,160,492.3333
If the quotient is a whole number, then 3 and 11,160,492.3333 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 | 33,481,477 | |
| -1 | -33,481,477 |
Let's try dividing by 4:
33,481,477 ÷ 4 = 8,370,369.25
If the quotient is a whole number, then 4 and 8,370,369.25 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 | 33,481,477 | |
| -1 | 33,481,477 |
If you did it right, you will end up with this table:
| 1 | 19 | 43 | 107 | 383 | 817 | 2,033 | 4,601 | 7,277 | 16,469 | 40,981 | 87,419 | 312,911 | 778,639 | 1,762,183 | 33,481,477 |
| -1 | -19 | -43 | -107 | -383 | -817 | -2,033 | -4,601 | -7,277 | -16,469 | -40,981 | -87,419 | -312,911 | -778,639 | -1,762,183 | -33,481,477 |
