How do I find the factor combinations of the number 238,589?

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 238,589, 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.

1 238,589
-1 -238,589

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 238,589.

Example:
1 x 238,589 = 238,589
and
-1 x -238,589 = 238,589
Notice both answers equal 238,589

With that explanation out of the way, let's continue. Next, we take the number 238,589 and divide it by 2:

238,589 ÷ 2 = 119,294.5

If the quotient is a whole number, then 2 and 119,294.5 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:

1 238,589
-1 -238,589

Now, we try dividing 238,589 by 3:

238,589 ÷ 3 = 79,529.6667

If the quotient is a whole number, then 3 and 79,529.6667 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:

1 238,589
-1 -238,589

Let's try dividing by 4:

238,589 ÷ 4 = 59,647.25

If the quotient is a whole number, then 4 and 59,647.25 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:

1 238,589
-1 238,589
Keep dividing by the next highest number until you cannot divide anymore.

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

11318,353238,589
-1-13-18,353-238,589
