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 200,133,137, 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 | 200,133,137 | |
| -1 | -200,133,137 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 200,133,137.
Example:
1 x 200,133,137 = 200,133,137
and
-1 x -200,133,137 = 200,133,137
Notice both answers equal 200,133,137
With that explanation out of the way, let's continue. Next, we take the number 200,133,137 and divide it by 2:
200,133,137 ÷ 2 = 100,066,568.5
If the quotient is a whole number, then 2 and 100,066,568.5 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 | 200,133,137 | |
| -1 | -200,133,137 |
Now, we try dividing 200,133,137 by 3:
200,133,137 ÷ 3 = 66,711,045.6667
If the quotient is a whole number, then 3 and 66,711,045.6667 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 | 200,133,137 | |
| -1 | -200,133,137 |
Let's try dividing by 4:
200,133,137 ÷ 4 = 50,033,284.25
If the quotient is a whole number, then 4 and 50,033,284.25 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 | 200,133,137 | |
| -1 | 200,133,137 |
If you did it right, you will end up with this table:
| 1 | 19 | 43 | 487 | 503 | 817 | 9,253 | 9,557 | 20,941 | 21,629 | 244,961 | 397,879 | 410,951 | 4,654,259 | 10,533,323 | 200,133,137 |
| -1 | -19 | -43 | -487 | -503 | -817 | -9,253 | -9,557 | -20,941 | -21,629 | -244,961 | -397,879 | -410,951 | -4,654,259 | -10,533,323 | -200,133,137 |
