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 33,130,511, 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 | 33,130,511 | |
| -1 | -33,130,511 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,130,511.
Example:
1 x 33,130,511 = 33,130,511
and
-1 x -33,130,511 = 33,130,511
Notice both answers equal 33,130,511
With that explanation out of the way, let's continue. Next, we take the number 33,130,511 and divide it by 2:
33,130,511 ÷ 2 = 16,565,255.5
If the quotient is a whole number, then 2 and 16,565,255.5 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 | 33,130,511 | |
| -1 | -33,130,511 |
Now, we try dividing 33,130,511 by 3:
33,130,511 ÷ 3 = 11,043,503.6667
If the quotient is a whole number, then 3 and 11,043,503.6667 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 | 33,130,511 | |
| -1 | -33,130,511 |
Let's try dividing by 4:
33,130,511 ÷ 4 = 8,282,627.75
If the quotient is a whole number, then 4 and 8,282,627.75 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 | 33,130,511 | |
| -1 | 33,130,511 |
If you did it right, you will end up with this table:
| 1 | 23 | 43 | 139 | 241 | 989 | 3,197 | 5,543 | 5,977 | 10,363 | 33,499 | 137,471 | 238,349 | 770,477 | 1,440,457 | 33,130,511 |
| -1 | -23 | -43 | -139 | -241 | -989 | -3,197 | -5,543 | -5,977 | -10,363 | -33,499 | -137,471 | -238,349 | -770,477 | -1,440,457 | -33,130,511 |
