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 202,218,317, 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 | 202,218,317 | |
-1 | -202,218,317 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 202,218,317.
Example:
1 x 202,218,317 = 202,218,317
and
-1 x -202,218,317 = 202,218,317
Notice both answers equal 202,218,317
With that explanation out of the way, let's continue. Next, we take the number 202,218,317 and divide it by 2:
202,218,317 ÷ 2 = 101,109,158.5
If the quotient is a whole number, then 2 and 101,109,158.5 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 | 202,218,317 | |
-1 | -202,218,317 |
Now, we try dividing 202,218,317 by 3:
202,218,317 ÷ 3 = 67,406,105.6667
If the quotient is a whole number, then 3 and 67,406,105.6667 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 | 202,218,317 | |
-1 | -202,218,317 |
Let's try dividing by 4:
202,218,317 ÷ 4 = 50,554,579.25
If the quotient is a whole number, then 4 and 50,554,579.25 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 | 202,218,317 | |
-1 | 202,218,317 |
If you did it right, you will end up with this table:
1 | 7 | 28,888,331 | 202,218,317 |
-1 | -7 | -28,888,331 | -202,218,317 |
