How do I find the factor combinations of the number 698,819?

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 698,819, 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.

1 698,819
-1 -698,819

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 698,819.

Example:
1 x 698,819 = 698,819
and
-1 x -698,819 = 698,819
Notice both answers equal 698,819

With that explanation out of the way, let's continue. Next, we take the number 698,819 and divide it by 2:

698,819 ÷ 2 = 349,409.5

If the quotient is a whole number, then 2 and 349,409.5 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:

1 698,819
-1 -698,819

Now, we try dividing 698,819 by 3:

698,819 ÷ 3 = 232,939.6667

If the quotient is a whole number, then 3 and 232,939.6667 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:

1 698,819
-1 -698,819

Let's try dividing by 4:

698,819 ÷ 4 = 174,704.75

If the quotient is a whole number, then 4 and 174,704.75 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:

1 698,819
-1 698,819
Keep dividing by the next highest number until you cannot divide anymore.

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

11117371011874076291,1111,7173,7376,91918,88741,10763,529698,819
