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 33,845,825, 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 | 33,845,825 | |
| -1 | -33,845,825 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,845,825.
Example:
1 x 33,845,825 = 33,845,825
and
-1 x -33,845,825 = 33,845,825
Notice both answers equal 33,845,825
With that explanation out of the way, let's continue. Next, we take the number 33,845,825 and divide it by 2:
33,845,825 ÷ 2 = 16,922,912.5
If the quotient is a whole number, then 2 and 16,922,912.5 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 | 33,845,825 | |
| -1 | -33,845,825 |
Now, we try dividing 33,845,825 by 3:
33,845,825 ÷ 3 = 11,281,941.6667
If the quotient is a whole number, then 3 and 11,281,941.6667 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 | 33,845,825 | |
| -1 | -33,845,825 |
Let's try dividing by 4:
33,845,825 ÷ 4 = 8,461,456.25
If the quotient is a whole number, then 4 and 8,461,456.25 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 | 33,845,825 | |
| -1 | 33,845,825 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 65 | 223 | 325 | 467 | 1,115 | 2,335 | 2,899 | 5,575 | 6,071 | 11,675 | 14,495 | 30,355 | 72,475 | 104,141 | 151,775 | 520,705 | 1,353,833 | 2,603,525 | 6,769,165 | 33,845,825 |
| -1 | -5 | -13 | -25 | -65 | -223 | -325 | -467 | -1,115 | -2,335 | -2,899 | -5,575 | -6,071 | -11,675 | -14,495 | -30,355 | -72,475 | -104,141 | -151,775 | -520,705 | -1,353,833 | -2,603,525 | -6,769,165 | -33,845,825 |
