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 33,291,445, 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 | 33,291,445 | |
| -1 | -33,291,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,291,445.
Example:
1 x 33,291,445 = 33,291,445
and
-1 x -33,291,445 = 33,291,445
Notice both answers equal 33,291,445
With that explanation out of the way, let's continue. Next, we take the number 33,291,445 and divide it by 2:
33,291,445 ÷ 2 = 16,645,722.5
If the quotient is a whole number, then 2 and 16,645,722.5 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 | 33,291,445 | |
| -1 | -33,291,445 |
Now, we try dividing 33,291,445 by 3:
33,291,445 ÷ 3 = 11,097,148.3333
If the quotient is a whole number, then 3 and 11,097,148.3333 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 | 33,291,445 | |
| -1 | -33,291,445 |
Let's try dividing by 4:
33,291,445 ÷ 4 = 8,322,861.25
If the quotient is a whole number, then 4 and 8,322,861.25 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 | 33,291,445 | |
| -1 | 33,291,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 107 | 535 | 1,177 | 5,657 | 5,885 | 28,285 | 62,227 | 311,135 | 605,299 | 3,026,495 | 6,658,289 | 33,291,445 |
| -1 | -5 | -11 | -55 | -107 | -535 | -1,177 | -5,657 | -5,885 | -28,285 | -62,227 | -311,135 | -605,299 | -3,026,495 | -6,658,289 | -33,291,445 |
