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 33,768,545, 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 | 33,768,545 | |
| -1 | -33,768,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,768,545.
Example:
1 x 33,768,545 = 33,768,545
and
-1 x -33,768,545 = 33,768,545
Notice both answers equal 33,768,545
With that explanation out of the way, let's continue. Next, we take the number 33,768,545 and divide it by 2:
33,768,545 ÷ 2 = 16,884,272.5
If the quotient is a whole number, then 2 and 16,884,272.5 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 | 33,768,545 | |
| -1 | -33,768,545 |
Now, we try dividing 33,768,545 by 3:
33,768,545 ÷ 3 = 11,256,181.6667
If the quotient is a whole number, then 3 and 11,256,181.6667 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 | 33,768,545 | |
| -1 | -33,768,545 |
Let's try dividing by 4:
33,768,545 ÷ 4 = 8,442,136.25
If the quotient is a whole number, then 4 and 8,442,136.25 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 | 33,768,545 | |
| -1 | 33,768,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 43 | 85 | 215 | 731 | 3,655 | 9,239 | 46,195 | 157,063 | 397,277 | 785,315 | 1,986,385 | 6,753,709 | 33,768,545 |
| -1 | -5 | -17 | -43 | -85 | -215 | -731 | -3,655 | -9,239 | -46,195 | -157,063 | -397,277 | -785,315 | -1,986,385 | -6,753,709 | -33,768,545 |
