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 845,395, 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 | 845,395 | |
-1 | -845,395 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 845,395.
Example:
1 x 845,395 = 845,395
and
-1 x -845,395 = 845,395
Notice both answers equal 845,395
With that explanation out of the way, let's continue. Next, we take the number 845,395 and divide it by 2:
845,395 ÷ 2 = 422,697.5
If the quotient is a whole number, then 2 and 422,697.5 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 | 845,395 | |
-1 | -845,395 |
Now, we try dividing 845,395 by 3:
845,395 ÷ 3 = 281,798.3333
If the quotient is a whole number, then 3 and 281,798.3333 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 | 845,395 | |
-1 | -845,395 |
Let's try dividing by 4:
845,395 ÷ 4 = 211,348.75
If the quotient is a whole number, then 4 and 211,348.75 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 | 845,395 | |
-1 | 845,395 |
If you did it right, you will end up with this table:
1 | 5 | 169,079 | 845,395 |
-1 | -5 | -169,079 | -845,395 |
