How do I find the factor combinations of the number 208,453?

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 208,453, 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.

1 208,453
-1 -208,453

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 208,453.

Example:
1 x 208,453 = 208,453
and
-1 x -208,453 = 208,453
Notice both answers equal 208,453

With that explanation out of the way, let's continue. Next, we take the number 208,453 and divide it by 2:

208,453 ÷ 2 = 104,226.5

If the quotient is a whole number, then 2 and 104,226.5 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:

1 208,453
-1 -208,453

Now, we try dividing 208,453 by 3:

208,453 ÷ 3 = 69,484.3333

If the quotient is a whole number, then 3 and 69,484.3333 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:

1 208,453
-1 -208,453

Let's try dividing by 4:

208,453 ÷ 4 = 52,113.25

If the quotient is a whole number, then 4 and 52,113.25 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:

1 208,453
-1 208,453
Keep dividing by the next highest number until you cannot divide anymore.

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

17973076792,14929,779208,453
-1-7-97-307-679-2,149-29,779-208,453
