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 33,505,585, 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 | 33,505,585 | |
| -1 | -33,505,585 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,505,585.
Example:
1 x 33,505,585 = 33,505,585
and
-1 x -33,505,585 = 33,505,585
Notice both answers equal 33,505,585
With that explanation out of the way, let's continue. Next, we take the number 33,505,585 and divide it by 2:
33,505,585 ÷ 2 = 16,752,792.5
If the quotient is a whole number, then 2 and 16,752,792.5 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 | 33,505,585 | |
| -1 | -33,505,585 |
Now, we try dividing 33,505,585 by 3:
33,505,585 ÷ 3 = 11,168,528.3333
If the quotient is a whole number, then 3 and 11,168,528.3333 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 | 33,505,585 | |
| -1 | -33,505,585 |
Let's try dividing by 4:
33,505,585 ÷ 4 = 8,376,396.25
If the quotient is a whole number, then 4 and 8,376,396.25 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 | 33,505,585 | |
| -1 | 33,505,585 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 145 | 311 | 743 | 1,555 | 3,715 | 9,019 | 21,547 | 45,095 | 107,735 | 231,073 | 1,155,365 | 6,701,117 | 33,505,585 |
| -1 | -5 | -29 | -145 | -311 | -743 | -1,555 | -3,715 | -9,019 | -21,547 | -45,095 | -107,735 | -231,073 | -1,155,365 | -6,701,117 | -33,505,585 |
