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 33,580,927, 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 | 33,580,927 | |
| -1 | -33,580,927 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,580,927.
Example:
1 x 33,580,927 = 33,580,927
and
-1 x -33,580,927 = 33,580,927
Notice both answers equal 33,580,927
With that explanation out of the way, let's continue. Next, we take the number 33,580,927 and divide it by 2:
33,580,927 ÷ 2 = 16,790,463.5
If the quotient is a whole number, then 2 and 16,790,463.5 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 | 33,580,927 | |
| -1 | -33,580,927 |
Now, we try dividing 33,580,927 by 3:
33,580,927 ÷ 3 = 11,193,642.3333
If the quotient is a whole number, then 3 and 11,193,642.3333 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 | 33,580,927 | |
| -1 | -33,580,927 |
Let's try dividing by 4:
33,580,927 ÷ 4 = 8,395,231.75
If the quotient is a whole number, then 4 and 8,395,231.75 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 | 33,580,927 | |
| -1 | 33,580,927 |
If you did it right, you will end up with this table:
| 1 | 29 | 41 | 61 | 463 | 1,189 | 1,769 | 2,501 | 13,427 | 18,983 | 28,243 | 72,529 | 550,507 | 819,047 | 1,157,963 | 33,580,927 |
| -1 | -29 | -41 | -61 | -463 | -1,189 | -1,769 | -2,501 | -13,427 | -18,983 | -28,243 | -72,529 | -550,507 | -819,047 | -1,157,963 | -33,580,927 |
