How do I find the factor combinations of the number 6,508,865?

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 6,508,865, 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 6,508,865
-1 -6,508,865

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 6,508,865.

Example:
1 x 6,508,865 = 6,508,865
and
-1 x -6,508,865 = 6,508,865
Notice both answers equal 6,508,865

With that explanation out of the way, let's continue. Next, we take the number 6,508,865 and divide it by 2:

6,508,865 ÷ 2 = 3,254,432.5

If the quotient is a whole number, then 2 and 3,254,432.5 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 6,508,865
-1 -6,508,865

Now, we try dividing 6,508,865 by 3:

6,508,865 ÷ 3 = 2,169,621.6667

If the quotient is a whole number, then 3 and 2,169,621.6667 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 6,508,865
-1 -6,508,865

Let's try dividing by 4:

6,508,865 ÷ 4 = 1,627,216.25

If the quotient is a whole number, then 4 and 1,627,216.25 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 6,508,865
-1 6,508,865
Keep dividing by the next highest number until you cannot divide anymore.

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

151155118,343591,7151,301,7736,508,865
-1-5-11-55-118,343-591,715-1,301,773-6,508,865
