How do I find the factor combinations of the number 727,276?

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 727,276, 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.

1 727,276
-1 -727,276

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 727,276.

Example:
1 x 727,276 = 727,276
and
-1 x -727,276 = 727,276
Notice both answers equal 727,276

With that explanation out of the way, let's continue. Next, we take the number 727,276 and divide it by 2:

727,276 ÷ 2 = 363,638

If the quotient is a whole number, then 2 and 363,638 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 2 363,638 727,276
-1 -2 -363,638 -727,276

Now, we try dividing 727,276 by 3:

727,276 ÷ 3 = 242,425.3333

If the quotient is a whole number, then 3 and 242,425.3333 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 2 363,638 727,276
-1 -2 -363,638 -727,276

Let's try dividing by 4:

727,276 ÷ 4 = 181,819

If the quotient is a whole number, then 4 and 181,819 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 4 181,819 363,638 727,276
-1 -2 -4 -181,819 -363,638 727,276
Keep dividing by the next highest number until you cannot divide anymore.

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

12411224416,52933,05866,116181,819363,638727,276
-1-2-4-11-22-44-16,529-33,058-66,116-181,819-363,638-727,276
