How do I find the factor combinations of the number 3,043,271?

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 3,043,271, 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 3,043,271
-1 -3,043,271

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 3,043,271.

Example:
1 x 3,043,271 = 3,043,271
and
-1 x -3,043,271 = 3,043,271
Notice both answers equal 3,043,271

With that explanation out of the way, let's continue. Next, we take the number 3,043,271 and divide it by 2:

3,043,271 ÷ 2 = 1,521,635.5

If the quotient is a whole number, then 2 and 1,521,635.5 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 3,043,271
-1 -3,043,271

Now, we try dividing 3,043,271 by 3:

3,043,271 ÷ 3 = 1,014,423.6667

If the quotient is a whole number, then 3 and 1,014,423.6667 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 3,043,271
-1 -3,043,271

Let's try dividing by 4:

3,043,271 ÷ 4 = 760,817.75

If the quotient is a whole number, then 4 and 760,817.75 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 3,043,271
-1 3,043,271
Keep dividing by the next highest number until you cannot divide anymore.

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

1711771218473,59325,15139,523276,661434,7533,043,271
