How do I find the factor combinations of the number 3,748,591?

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 3,748,591, 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 3,748,591
-1 -3,748,591

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 3,748,591.

Example:
1 x 3,748,591 = 3,748,591
and
-1 x -3,748,591 = 3,748,591
Notice both answers equal 3,748,591

With that explanation out of the way, let's continue. Next, we take the number 3,748,591 and divide it by 2:

3,748,591 ÷ 2 = 1,874,295.5

If the quotient is a whole number, then 2 and 1,874,295.5 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 3,748,591
-1 -3,748,591

Now, we try dividing 3,748,591 by 3:

3,748,591 ÷ 3 = 1,249,530.3333

If the quotient is a whole number, then 3 and 1,249,530.3333 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 3,748,591
-1 -3,748,591

Let's try dividing by 4:

3,748,591 ÷ 4 = 937,147.75

If the quotient is a whole number, then 4 and 937,147.75 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 3,748,591
-1 3,748,591
Keep dividing by the next highest number until you cannot divide anymore.

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

171177895476239793,8296,0176,85342,11948,683340,781535,5133,748,591
