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 451,135, 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 | 451,135 | |
-1 | -451,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 451,135.
Example:
1 x 451,135 = 451,135
and
-1 x -451,135 = 451,135
Notice both answers equal 451,135
With that explanation out of the way, let's continue. Next, we take the number 451,135 and divide it by 2:
451,135 ÷ 2 = 225,567.5
If the quotient is a whole number, then 2 and 225,567.5 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 | 451,135 | |
-1 | -451,135 |
Now, we try dividing 451,135 by 3:
451,135 ÷ 3 = 150,378.3333
If the quotient is a whole number, then 3 and 150,378.3333 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 | 451,135 | |
-1 | -451,135 |
Let's try dividing by 4:
451,135 ÷ 4 = 112,783.75
If the quotient is a whole number, then 4 and 112,783.75 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 | 451,135 | |
-1 | 451,135 |
If you did it right, you will end up with this table:
1 | 5 | 90,227 | 451,135 |
-1 | -5 | -90,227 | -451,135 |
