How do I find the factor combinations of the number 6,947,615?

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 6,947,615, 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 6,947,615
-1 -6,947,615

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 6,947,615.

Example:
1 x 6,947,615 = 6,947,615
and
-1 x -6,947,615 = 6,947,615
Notice both answers equal 6,947,615

With that explanation out of the way, let's continue. Next, we take the number 6,947,615 and divide it by 2:

6,947,615 ÷ 2 = 3,473,807.5

If the quotient is a whole number, then 2 and 3,473,807.5 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 6,947,615
-1 -6,947,615

Now, we try dividing 6,947,615 by 3:

6,947,615 ÷ 3 = 2,315,871.6667

If the quotient is a whole number, then 3 and 2,315,871.6667 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 6,947,615
-1 -6,947,615

Let's try dividing by 4:

6,947,615 ÷ 4 = 1,736,903.75

If the quotient is a whole number, then 4 and 1,736,903.75 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 6,947,615
-1 6,947,615
Keep dividing by the next highest number until you cannot divide anymore.

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

156432,1613,21510,8051,389,5236,947,615
-1-5-643-2,161-3,215-10,805-1,389,523-6,947,615
