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 33,508,853, 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 | 33,508,853 | |
| -1 | -33,508,853 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,508,853.
Example:
1 x 33,508,853 = 33,508,853
and
-1 x -33,508,853 = 33,508,853
Notice both answers equal 33,508,853
With that explanation out of the way, let's continue. Next, we take the number 33,508,853 and divide it by 2:
33,508,853 ÷ 2 = 16,754,426.5
If the quotient is a whole number, then 2 and 16,754,426.5 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 | 33,508,853 | |
| -1 | -33,508,853 |
Now, we try dividing 33,508,853 by 3:
33,508,853 ÷ 3 = 11,169,617.6667
If the quotient is a whole number, then 3 and 11,169,617.6667 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 | 33,508,853 | |
| -1 | -33,508,853 |
Let's try dividing by 4:
33,508,853 ÷ 4 = 8,377,213.25
If the quotient is a whole number, then 4 and 8,377,213.25 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 | 33,508,853 | |
| -1 | 33,508,853 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 193 | 1,351 | 1,459 | 3,281 | 10,213 | 22,967 | 24,803 | 173,621 | 281,587 | 1,971,109 | 4,786,979 | 33,508,853 |
| -1 | -7 | -17 | -119 | -193 | -1,351 | -1,459 | -3,281 | -10,213 | -22,967 | -24,803 | -173,621 | -281,587 | -1,971,109 | -4,786,979 | -33,508,853 |
