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 200,200,315, 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 | 200,200,315 | |
| -1 | -200,200,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 200,200,315.
Example:
1 x 200,200,315 = 200,200,315
and
-1 x -200,200,315 = 200,200,315
Notice both answers equal 200,200,315
With that explanation out of the way, let's continue. Next, we take the number 200,200,315 and divide it by 2:
200,200,315 ÷ 2 = 100,100,157.5
If the quotient is a whole number, then 2 and 100,100,157.5 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 | 200,200,315 | |
| -1 | -200,200,315 |
Now, we try dividing 200,200,315 by 3:
200,200,315 ÷ 3 = 66,733,438.3333
If the quotient is a whole number, then 3 and 66,733,438.3333 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 | 200,200,315 | |
| -1 | -200,200,315 |
Let's try dividing by 4:
200,200,315 ÷ 4 = 50,050,078.75
If the quotient is a whole number, then 4 and 50,050,078.75 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 | 200,200,315 | |
| -1 | 200,200,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 2,237 | 2,557 | 11,185 | 12,785 | 15,659 | 17,899 | 78,295 | 89,495 | 5,720,009 | 28,600,045 | 40,040,063 | 200,200,315 |
| -1 | -5 | -7 | -35 | -2,237 | -2,557 | -11,185 | -12,785 | -15,659 | -17,899 | -78,295 | -89,495 | -5,720,009 | -28,600,045 | -40,040,063 | -200,200,315 |
