How do I find the factor combinations of the number 799,669?

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 799,669, 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.

1 799,669
-1 -799,669

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 799,669.

Example:
1 x 799,669 = 799,669
and
-1 x -799,669 = 799,669
Notice both answers equal 799,669

With that explanation out of the way, let's continue. Next, we take the number 799,669 and divide it by 2:

799,669 ÷ 2 = 399,834.5

If the quotient is a whole number, then 2 and 399,834.5 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:

1 799,669
-1 -799,669

Now, we try dividing 799,669 by 3:

799,669 ÷ 3 = 266,556.3333

If the quotient is a whole number, then 3 and 266,556.3333 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:

1 799,669
-1 -799,669

Let's try dividing by 4:

799,669 ÷ 4 = 199,917.25

If the quotient is a whole number, then 4 and 199,917.25 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:

1 799,669
-1 799,669
Keep dividing by the next highest number until you cannot divide anymore.

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

1131374491,7815,83761,513799,669
-1-13-137-449-1,781-5,837-61,513-799,669
