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 33,788,915, 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 | 33,788,915 | |
| -1 | -33,788,915 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,788,915.
Example:
1 x 33,788,915 = 33,788,915
and
-1 x -33,788,915 = 33,788,915
Notice both answers equal 33,788,915
With that explanation out of the way, let's continue. Next, we take the number 33,788,915 and divide it by 2:
33,788,915 ÷ 2 = 16,894,457.5
If the quotient is a whole number, then 2 and 16,894,457.5 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 | 33,788,915 | |
| -1 | -33,788,915 |
Now, we try dividing 33,788,915 by 3:
33,788,915 ÷ 3 = 11,262,971.6667
If the quotient is a whole number, then 3 and 11,262,971.6667 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 | 33,788,915 | |
| -1 | -33,788,915 |
Let's try dividing by 4:
33,788,915 ÷ 4 = 8,447,228.75
If the quotient is a whole number, then 4 and 8,447,228.75 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 | 33,788,915 | |
| -1 | 33,788,915 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 31 | 145 | 155 | 899 | 4,495 | 7,517 | 37,585 | 217,993 | 233,027 | 1,089,965 | 1,165,135 | 6,757,783 | 33,788,915 |
| -1 | -5 | -29 | -31 | -145 | -155 | -899 | -4,495 | -7,517 | -37,585 | -217,993 | -233,027 | -1,089,965 | -1,165,135 | -6,757,783 | -33,788,915 |
