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 323,162,017, 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 | 323,162,017 | |
-1 | -323,162,017 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 323,162,017.
Example:
1 x 323,162,017 = 323,162,017
and
-1 x -323,162,017 = 323,162,017
Notice both answers equal 323,162,017
With that explanation out of the way, let's continue. Next, we take the number 323,162,017 and divide it by 2:
323,162,017 ÷ 2 = 161,581,008.5
If the quotient is a whole number, then 2 and 161,581,008.5 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 | 323,162,017 | |
-1 | -323,162,017 |
Now, we try dividing 323,162,017 by 3:
323,162,017 ÷ 3 = 107,720,672.3333
If the quotient is a whole number, then 3 and 107,720,672.3333 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 | 323,162,017 | |
-1 | -323,162,017 |
Let's try dividing by 4:
323,162,017 ÷ 4 = 80,790,504.25
If the quotient is a whole number, then 4 and 80,790,504.25 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 | 323,162,017 | |
-1 | 323,162,017 |
If you did it right, you will end up with this table:
1 | 2,003 | 161,339 | 323,162,017 |
-1 | -2,003 | -161,339 | -323,162,017 |
