How do I find the factor combinations of the number 774,768?

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 774,768, 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.

1 774,768
-1 -774,768

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 774,768.

Example:
1 x 774,768 = 774,768
and
-1 x -774,768 = 774,768
Notice both answers equal 774,768

With that explanation out of the way, let's continue. Next, we take the number 774,768 and divide it by 2:

774,768 ÷ 2 = 387,384

If the quotient is a whole number, then 2 and 387,384 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 2 387,384 774,768
-1 -2 -387,384 -774,768

Now, we try dividing 774,768 by 3:

774,768 ÷ 3 = 258,256

If the quotient is a whole number, then 3 and 258,256 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 3 258,256 387,384 774,768
-1 -2 -3 -258,256 -387,384 -774,768

Let's try dividing by 4:

774,768 ÷ 4 = 193,692

If the quotient is a whole number, then 4 and 193,692 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 4 193,692 258,256 387,384 774,768
-1 -2 -3 -4 -193,692 -258,256 -387,384 774,768
Keep dividing by the next highest number until you cannot divide anymore.

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