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 200,311,321, 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 | 200,311,321 | |
| -1 | -200,311,321 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 200,311,321.
Example:
1 x 200,311,321 = 200,311,321
and
-1 x -200,311,321 = 200,311,321
Notice both answers equal 200,311,321
With that explanation out of the way, let's continue. Next, we take the number 200,311,321 and divide it by 2:
200,311,321 ÷ 2 = 100,155,660.5
If the quotient is a whole number, then 2 and 100,155,660.5 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 | 200,311,321 | |
| -1 | -200,311,321 |
Now, we try dividing 200,311,321 by 3:
200,311,321 ÷ 3 = 66,770,440.3333
If the quotient is a whole number, then 3 and 66,770,440.3333 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 | 200,311,321 | |
| -1 | -200,311,321 |
Let's try dividing by 4:
200,311,321 ÷ 4 = 50,077,830.25
If the quotient is a whole number, then 4 and 50,077,830.25 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 | 200,311,321 | |
| -1 | 200,311,321 |
If you did it right, you will end up with this table:
| 1 | 7 | 47 | 89 | 329 | 623 | 4,183 | 6,841 | 29,281 | 47,887 | 321,527 | 608,849 | 2,250,689 | 4,261,943 | 28,615,903 | 200,311,321 |
| -1 | -7 | -47 | -89 | -329 | -623 | -4,183 | -6,841 | -29,281 | -47,887 | -321,527 | -608,849 | -2,250,689 | -4,261,943 | -28,615,903 | -200,311,321 |
