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 455,395, 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 | 455,395 | |
-1 | -455,395 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 455,395.
Example:
1 x 455,395 = 455,395
and
-1 x -455,395 = 455,395
Notice both answers equal 455,395
With that explanation out of the way, let's continue. Next, we take the number 455,395 and divide it by 2:
455,395 ÷ 2 = 227,697.5
If the quotient is a whole number, then 2 and 227,697.5 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 | 455,395 | |
-1 | -455,395 |
Now, we try dividing 455,395 by 3:
455,395 ÷ 3 = 151,798.3333
If the quotient is a whole number, then 3 and 151,798.3333 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 | 455,395 | |
-1 | -455,395 |
Let's try dividing by 4:
455,395 ÷ 4 = 113,848.75
If the quotient is a whole number, then 4 and 113,848.75 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 | 455,395 | |
-1 | 455,395 |
If you did it right, you will end up with this table:
1 | 5 | 91,079 | 455,395 |
-1 | -5 | -91,079 | -455,395 |
