How do I find the factor combinations of the number 194,821?

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 194,821, 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.

1 194,821
-1 -194,821

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 194,821.

Example:
1 x 194,821 = 194,821
and
-1 x -194,821 = 194,821
Notice both answers equal 194,821

With that explanation out of the way, let's continue. Next, we take the number 194,821 and divide it by 2:

194,821 ÷ 2 = 97,410.5

If the quotient is a whole number, then 2 and 97,410.5 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:

1 194,821
-1 -194,821

Now, we try dividing 194,821 by 3:

194,821 ÷ 3 = 64,940.3333

If the quotient is a whole number, then 3 and 64,940.3333 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:

1 194,821
-1 -194,821

Let's try dividing by 4:

194,821 ÷ 4 = 48,705.25

If the quotient is a whole number, then 4 and 48,705.25 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:

1 194,821
-1 194,821
Keep dividing by the next highest number until you cannot divide anymore.

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

111891999792,18917,711194,821
-1-11-89-199-979-2,189-17,711-194,821
