How do I find the factor combinations of the number 776,820?

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 776,820, 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.

1 776,820
-1 -776,820

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 776,820.

Example:
1 x 776,820 = 776,820
and
-1 x -776,820 = 776,820
Notice both answers equal 776,820

With that explanation out of the way, let's continue. Next, we take the number 776,820 and divide it by 2:

776,820 ÷ 2 = 388,410

If the quotient is a whole number, then 2 and 388,410 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 2 388,410 776,820
-1 -2 -388,410 -776,820

Now, we try dividing 776,820 by 3:

776,820 ÷ 3 = 258,940

If the quotient is a whole number, then 3 and 258,940 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 3 258,940 388,410 776,820
-1 -2 -3 -258,940 -388,410 -776,820

Let's try dividing by 4:

776,820 ÷ 4 = 194,205

If the quotient is a whole number, then 4 and 194,205 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 4 194,205 258,940 388,410 776,820
-1 -2 -3 -4 -194,205 -258,940 -388,410 776,820
Keep dividing by the next highest number until you cannot divide anymore.

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