How do I find the factor combinations of the number 478,795?

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 478,795, it is easier to work with a table - it's called factoring from the outside in.

Outside in Factoring

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.

1 478,795
-1 -478,795

Why are the negative numbers included?

When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 478,795.

Example:
1 x 478,795 = 478,795
and
-1 x -478,795 = 478,795
Notice both answers equal 478,795

With that explanation out of the way, let's continue. Next, we take the number 478,795 and divide it by 2:

478,795 ÷ 2 = 239,397.5

If the quotient is a whole number, then 2 and 239,397.5 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:

1 478,795
-1 -478,795

Now, we try dividing 478,795 by 3:

478,795 ÷ 3 = 159,598.3333

If the quotient is a whole number, then 3 and 159,598.3333 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:

1 478,795
-1 -478,795

Let's try dividing by 4:

478,795 ÷ 4 = 119,698.75

If the quotient is a whole number, then 4 and 119,698.75 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:

1 478,795
-1 478,795
Keep dividing by the next highest number until you cannot divide anymore.

If you did it right, you will end up with this table:

15311553,08915,44595,759478,795
-1-5-31-155-3,089-15,445-95,759-478,795
