How do I find the factor combinations of the number 6,378,085?

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 6,378,085, 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 6,378,085
-1 -6,378,085

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 6,378,085.

Example:
1 x 6,378,085 = 6,378,085
and
-1 x -6,378,085 = 6,378,085
Notice both answers equal 6,378,085

With that explanation out of the way, let's continue. Next, we take the number 6,378,085 and divide it by 2:

6,378,085 ÷ 2 = 3,189,042.5

If the quotient is a whole number, then 2 and 3,189,042.5 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 6,378,085
-1 -6,378,085

Now, we try dividing 6,378,085 by 3:

6,378,085 ÷ 3 = 2,126,028.3333

If the quotient is a whole number, then 3 and 2,126,028.3333 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 6,378,085
-1 -6,378,085

Let's try dividing by 4:

6,378,085 ÷ 4 = 1,594,521.25

If the quotient is a whole number, then 4 and 1,594,521.25 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 6,378,085
-1 6,378,085
Keep dividing by the next highest number until you cannot divide anymore.

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