How do I find the factor combinations of the number 2,196,733?

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 2,196,733, 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 2,196,733
-1 -2,196,733

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 2,196,733.

Example:
1 x 2,196,733 = 2,196,733
and
-1 x -2,196,733 = 2,196,733
Notice both answers equal 2,196,733

With that explanation out of the way, let's continue. Next, we take the number 2,196,733 and divide it by 2:

2,196,733 ÷ 2 = 1,098,366.5

If the quotient is a whole number, then 2 and 1,098,366.5 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 2,196,733
-1 -2,196,733

Now, we try dividing 2,196,733 by 3:

2,196,733 ÷ 3 = 732,244.3333

If the quotient is a whole number, then 3 and 732,244.3333 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 2,196,733
-1 -2,196,733

Let's try dividing by 4:

2,196,733 ÷ 4 = 549,183.25

If the quotient is a whole number, then 4 and 549,183.25 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 2,196,733
-1 2,196,733
Keep dividing by the next highest number until you cannot divide anymore.

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

171147773295176073,6194,2496,67728,52946,739199,703313,8192,196,733
