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 664,775, 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 | 664,775 | |
-1 | -664,775 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 664,775.
Example:
1 x 664,775 = 664,775
and
-1 x -664,775 = 664,775
Notice both answers equal 664,775
With that explanation out of the way, let's continue. Next, we take the number 664,775 and divide it by 2:
664,775 ÷ 2 = 332,387.5
If the quotient is a whole number, then 2 and 332,387.5 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 | 664,775 | |
-1 | -664,775 |
Now, we try dividing 664,775 by 3:
664,775 ÷ 3 = 221,591.6667
If the quotient is a whole number, then 3 and 221,591.6667 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 | 664,775 | |
-1 | -664,775 |
Let's try dividing by 4:
664,775 ÷ 4 = 166,193.75
If the quotient is a whole number, then 4 and 166,193.75 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 | 664,775 | |
-1 | 664,775 |
If you did it right, you will end up with this table:
1 | 5 | 25 | 26,591 | 132,955 | 664,775 |
-1 | -5 | -25 | -26,591 | -132,955 | -664,775 |
