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 33,301,213, 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 | 33,301,213 | |
| -1 | -33,301,213 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,301,213.
Example:
1 x 33,301,213 = 33,301,213
and
-1 x -33,301,213 = 33,301,213
Notice both answers equal 33,301,213
With that explanation out of the way, let's continue. Next, we take the number 33,301,213 and divide it by 2:
33,301,213 ÷ 2 = 16,650,606.5
If the quotient is a whole number, then 2 and 16,650,606.5 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 | 33,301,213 | |
| -1 | -33,301,213 |
Now, we try dividing 33,301,213 by 3:
33,301,213 ÷ 3 = 11,100,404.3333
If the quotient is a whole number, then 3 and 11,100,404.3333 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 | 33,301,213 | |
| -1 | -33,301,213 |
Let's try dividing by 4:
33,301,213 ÷ 4 = 8,325,303.25
If the quotient is a whole number, then 4 and 8,325,303.25 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 | 33,301,213 | |
| -1 | 33,301,213 |
If you did it right, you will end up with this table:
| 1 | 11 | 73 | 113 | 367 | 803 | 1,243 | 4,037 | 8,249 | 26,791 | 41,471 | 90,739 | 294,701 | 456,181 | 3,027,383 | 33,301,213 |
| -1 | -11 | -73 | -113 | -367 | -803 | -1,243 | -4,037 | -8,249 | -26,791 | -41,471 | -90,739 | -294,701 | -456,181 | -3,027,383 | -33,301,213 |
