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 33,218,785, 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 | 33,218,785 | |
| -1 | -33,218,785 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,218,785.
Example:
1 x 33,218,785 = 33,218,785
and
-1 x -33,218,785 = 33,218,785
Notice both answers equal 33,218,785
With that explanation out of the way, let's continue. Next, we take the number 33,218,785 and divide it by 2:
33,218,785 ÷ 2 = 16,609,392.5
If the quotient is a whole number, then 2 and 16,609,392.5 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 | 33,218,785 | |
| -1 | -33,218,785 |
Now, we try dividing 33,218,785 by 3:
33,218,785 ÷ 3 = 11,072,928.3333
If the quotient is a whole number, then 3 and 11,072,928.3333 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 | 33,218,785 | |
| -1 | -33,218,785 |
Let's try dividing by 4:
33,218,785 ÷ 4 = 8,304,696.25
If the quotient is a whole number, then 4 and 8,304,696.25 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 | 33,218,785 | |
| -1 | 33,218,785 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 37 | 115 | 185 | 211 | 851 | 1,055 | 1,369 | 4,255 | 4,853 | 6,845 | 7,807 | 24,265 | 31,487 | 39,035 | 157,435 | 179,561 | 288,859 | 897,805 | 1,444,295 | 6,643,757 | 33,218,785 |
| -1 | -5 | -23 | -37 | -115 | -185 | -211 | -851 | -1,055 | -1,369 | -4,255 | -4,853 | -6,845 | -7,807 | -24,265 | -31,487 | -39,035 | -157,435 | -179,561 | -288,859 | -897,805 | -1,444,295 | -6,643,757 | -33,218,785 |
