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 200,550,133, 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 | 200,550,133 | |
| -1 | -200,550,133 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 200,550,133.
Example:
1 x 200,550,133 = 200,550,133
and
-1 x -200,550,133 = 200,550,133
Notice both answers equal 200,550,133
With that explanation out of the way, let's continue. Next, we take the number 200,550,133 and divide it by 2:
200,550,133 ÷ 2 = 100,275,066.5
If the quotient is a whole number, then 2 and 100,275,066.5 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 | 200,550,133 | |
| -1 | -200,550,133 |
Now, we try dividing 200,550,133 by 3:
200,550,133 ÷ 3 = 66,850,044.3333
If the quotient is a whole number, then 3 and 66,850,044.3333 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 | 200,550,133 | |
| -1 | -200,550,133 |
Let's try dividing by 4:
200,550,133 ÷ 4 = 50,137,533.25
If the quotient is a whole number, then 4 and 50,137,533.25 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 | 200,550,133 | |
| -1 | 200,550,133 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 161 | 167 | 1,169 | 3,841 | 7,459 | 26,887 | 52,213 | 171,557 | 1,200,899 | 1,245,653 | 8,719,571 | 28,650,019 | 200,550,133 |
| -1 | -7 | -23 | -161 | -167 | -1,169 | -3,841 | -7,459 | -26,887 | -52,213 | -171,557 | -1,200,899 | -1,245,653 | -8,719,571 | -28,650,019 | -200,550,133 |
