How do I find the factor combinations of the number 724,608?

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 724,608, 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.

1 724,608
-1 -724,608

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 724,608.

Example:
1 x 724,608 = 724,608
and
-1 x -724,608 = 724,608
Notice both answers equal 724,608

With that explanation out of the way, let's continue. Next, we take the number 724,608 and divide it by 2:

724,608 ÷ 2 = 362,304

If the quotient is a whole number, then 2 and 362,304 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 2 362,304 724,608
-1 -2 -362,304 -724,608

Now, we try dividing 724,608 by 3:

724,608 ÷ 3 = 241,536

If the quotient is a whole number, then 3 and 241,536 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 3 241,536 362,304 724,608
-1 -2 -3 -241,536 -362,304 -724,608

Let's try dividing by 4:

724,608 ÷ 4 = 181,152

If the quotient is a whole number, then 4 and 181,152 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 4 181,152 241,536 362,304 724,608
-1 -2 -3 -4 -181,152 -241,536 -362,304 724,608
Keep dividing by the next highest number until you cannot divide anymore.

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