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 33,610,405, 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 | 33,610,405 | |
| -1 | -33,610,405 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,610,405.
Example:
1 x 33,610,405 = 33,610,405
and
-1 x -33,610,405 = 33,610,405
Notice both answers equal 33,610,405
With that explanation out of the way, let's continue. Next, we take the number 33,610,405 and divide it by 2:
33,610,405 ÷ 2 = 16,805,202.5
If the quotient is a whole number, then 2 and 16,805,202.5 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 | 33,610,405 | |
| -1 | -33,610,405 |
Now, we try dividing 33,610,405 by 3:
33,610,405 ÷ 3 = 11,203,468.3333
If the quotient is a whole number, then 3 and 11,203,468.3333 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 | 33,610,405 | |
| -1 | -33,610,405 |
Let's try dividing by 4:
33,610,405 ÷ 4 = 8,402,601.25
If the quotient is a whole number, then 4 and 8,402,601.25 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 | 33,610,405 | |
| -1 | 33,610,405 |
If you did it right, you will end up with this table:
| 1 | 5 | 47 | 89 | 235 | 445 | 1,607 | 4,183 | 8,035 | 20,915 | 75,529 | 143,023 | 377,645 | 715,115 | 6,722,081 | 33,610,405 |
| -1 | -5 | -47 | -89 | -235 | -445 | -1,607 | -4,183 | -8,035 | -20,915 | -75,529 | -143,023 | -377,645 | -715,115 | -6,722,081 | -33,610,405 |
