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 33,122,185, 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 | 33,122,185 | |
| -1 | -33,122,185 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,122,185.
Example:
1 x 33,122,185 = 33,122,185
and
-1 x -33,122,185 = 33,122,185
Notice both answers equal 33,122,185
With that explanation out of the way, let's continue. Next, we take the number 33,122,185 and divide it by 2:
33,122,185 ÷ 2 = 16,561,092.5
If the quotient is a whole number, then 2 and 16,561,092.5 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 | 33,122,185 | |
| -1 | -33,122,185 |
Now, we try dividing 33,122,185 by 3:
33,122,185 ÷ 3 = 11,040,728.3333
If the quotient is a whole number, then 3 and 11,040,728.3333 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 | 33,122,185 | |
| -1 | -33,122,185 |
Let's try dividing by 4:
33,122,185 ÷ 4 = 8,280,546.25
If the quotient is a whole number, then 4 and 8,280,546.25 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 | 33,122,185 | |
| -1 | 33,122,185 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 293 | 983 | 1,465 | 4,915 | 6,739 | 22,609 | 33,695 | 113,045 | 288,019 | 1,440,095 | 6,624,437 | 33,122,185 |
| -1 | -5 | -23 | -115 | -293 | -983 | -1,465 | -4,915 | -6,739 | -22,609 | -33,695 | -113,045 | -288,019 | -1,440,095 | -6,624,437 | -33,122,185 |
