How do I find the factor combinations of the number 178,969?

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 178,969, 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.

1 178,969
-1 -178,969

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 178,969.

Example:
1 x 178,969 = 178,969
and
-1 x -178,969 = 178,969
Notice both answers equal 178,969

With that explanation out of the way, let's continue. Next, we take the number 178,969 and divide it by 2:

178,969 ÷ 2 = 89,484.5

If the quotient is a whole number, then 2 and 89,484.5 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:

1 178,969
-1 -178,969

Now, we try dividing 178,969 by 3:

178,969 ÷ 3 = 59,656.3333

If the quotient is a whole number, then 3 and 59,656.3333 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:

1 178,969
-1 -178,969

Let's try dividing by 4:

178,969 ÷ 4 = 44,742.25

If the quotient is a whole number, then 4 and 44,742.25 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:

1 178,969
-1 178,969
Keep dividing by the next highest number until you cannot divide anymore.

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

17372596914,83725,567178,969
-1-7-37-259-691-4,837-25,567-178,969
