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 200,200,319, 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 | 200,200,319 | |
| -1 | -200,200,319 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 200,200,319.
Example:
1 x 200,200,319 = 200,200,319
and
-1 x -200,200,319 = 200,200,319
Notice both answers equal 200,200,319
With that explanation out of the way, let's continue. Next, we take the number 200,200,319 and divide it by 2:
200,200,319 ÷ 2 = 100,100,159.5
If the quotient is a whole number, then 2 and 100,100,159.5 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 | 200,200,319 | |
| -1 | -200,200,319 |
Now, we try dividing 200,200,319 by 3:
200,200,319 ÷ 3 = 66,733,439.6667
If the quotient is a whole number, then 3 and 66,733,439.6667 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 | 200,200,319 | |
| -1 | -200,200,319 |
Let's try dividing by 4:
200,200,319 ÷ 4 = 50,050,079.75
If the quotient is a whole number, then 4 and 50,050,079.75 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 | 200,200,319 | |
| -1 | 200,200,319 |
If you did it right, you will end up with this table:
| 1 | 11 | 3,371 | 5,399 | 37,081 | 59,389 | 18,200,029 | 200,200,319 |
| -1 | -11 | -3,371 | -5,399 | -37,081 | -59,389 | -18,200,029 | -200,200,319 |
