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 33,300,995, 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 | 33,300,995 | |
| -1 | -33,300,995 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,300,995.
Example:
1 x 33,300,995 = 33,300,995
and
-1 x -33,300,995 = 33,300,995
Notice both answers equal 33,300,995
With that explanation out of the way, let's continue. Next, we take the number 33,300,995 and divide it by 2:
33,300,995 ÷ 2 = 16,650,497.5
If the quotient is a whole number, then 2 and 16,650,497.5 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 | 33,300,995 | |
| -1 | -33,300,995 |
Now, we try dividing 33,300,995 by 3:
33,300,995 ÷ 3 = 11,100,331.6667
If the quotient is a whole number, then 3 and 11,100,331.6667 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 | 33,300,995 | |
| -1 | -33,300,995 |
Let's try dividing by 4:
33,300,995 ÷ 4 = 8,325,248.75
If the quotient is a whole number, then 4 and 8,325,248.75 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 | 33,300,995 | |
| -1 | 33,300,995 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 65 | 91 | 455 | 73,189 | 365,945 | 512,323 | 951,457 | 2,561,615 | 4,757,285 | 6,660,199 | 33,300,995 |
| -1 | -5 | -7 | -13 | -35 | -65 | -91 | -455 | -73,189 | -365,945 | -512,323 | -951,457 | -2,561,615 | -4,757,285 | -6,660,199 | -33,300,995 |
