How do I find the factor combinations of the number 727,734?

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 727,734, 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.

1 727,734
-1 -727,734

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 727,734.

Example:
1 x 727,734 = 727,734
and
-1 x -727,734 = 727,734
Notice both answers equal 727,734

With that explanation out of the way, let's continue. Next, we take the number 727,734 and divide it by 2:

727,734 ÷ 2 = 363,867

If the quotient is a whole number, then 2 and 363,867 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!

Here is what our table should look like at this step:

1 2 363,867 727,734
-1 -2 -363,867 -727,734

Now, we try dividing 727,734 by 3:

727,734 ÷ 3 = 242,578

If the quotient is a whole number, then 3 and 242,578 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!

Here is what our table should look like at this step:

1 2 3 242,578 363,867 727,734
-1 -2 -3 -242,578 -363,867 -727,734

Let's try dividing by 4:

727,734 ÷ 4 = 181,933.5

If the quotient is a whole number, then 4 and 181,933.5 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 3 242,578 363,867 727,734
-1 -2 -3 -242,578 -363,867 727,734
Keep dividing by the next highest number until you cannot divide anymore.

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

1236714214217,32734,65451,981103,962121,289242,578363,867727,734
