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 33,512,765, 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 | 33,512,765 | |
| -1 | -33,512,765 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,512,765.
Example:
1 x 33,512,765 = 33,512,765
and
-1 x -33,512,765 = 33,512,765
Notice both answers equal 33,512,765
With that explanation out of the way, let's continue. Next, we take the number 33,512,765 and divide it by 2:
33,512,765 ÷ 2 = 16,756,382.5
If the quotient is a whole number, then 2 and 16,756,382.5 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 | 33,512,765 | |
| -1 | -33,512,765 |
Now, we try dividing 33,512,765 by 3:
33,512,765 ÷ 3 = 11,170,921.6667
If the quotient is a whole number, then 3 and 11,170,921.6667 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 | 33,512,765 | |
| -1 | -33,512,765 |
Let's try dividing by 4:
33,512,765 ÷ 4 = 8,378,191.25
If the quotient is a whole number, then 4 and 8,378,191.25 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 | 33,512,765 | |
| -1 | 33,512,765 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 55 | 65 | 121 | 143 | 605 | 715 | 1,573 | 4,261 | 7,865 | 21,305 | 46,871 | 55,393 | 234,355 | 276,965 | 515,581 | 609,323 | 2,577,905 | 3,046,615 | 6,702,553 | 33,512,765 |
| -1 | -5 | -11 | -13 | -55 | -65 | -121 | -143 | -605 | -715 | -1,573 | -4,261 | -7,865 | -21,305 | -46,871 | -55,393 | -234,355 | -276,965 | -515,581 | -609,323 | -2,577,905 | -3,046,615 | -6,702,553 | -33,512,765 |
