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 33,200,545, 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 | 33,200,545 | |
| -1 | -33,200,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,200,545.
Example:
1 x 33,200,545 = 33,200,545
and
-1 x -33,200,545 = 33,200,545
Notice both answers equal 33,200,545
With that explanation out of the way, let's continue. Next, we take the number 33,200,545 and divide it by 2:
33,200,545 ÷ 2 = 16,600,272.5
If the quotient is a whole number, then 2 and 16,600,272.5 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 | 33,200,545 | |
| -1 | -33,200,545 |
Now, we try dividing 33,200,545 by 3:
33,200,545 ÷ 3 = 11,066,848.3333
If the quotient is a whole number, then 3 and 11,066,848.3333 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 | 33,200,545 | |
| -1 | -33,200,545 |
Let's try dividing by 4:
33,200,545 ÷ 4 = 8,300,136.25
If the quotient is a whole number, then 4 and 8,300,136.25 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 | 33,200,545 | |
| -1 | 33,200,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 257 | 1,285 | 1,799 | 3,691 | 8,995 | 18,455 | 25,837 | 129,185 | 948,587 | 4,742,935 | 6,640,109 | 33,200,545 |
| -1 | -5 | -7 | -35 | -257 | -1,285 | -1,799 | -3,691 | -8,995 | -18,455 | -25,837 | -129,185 | -948,587 | -4,742,935 | -6,640,109 | -33,200,545 |
