How do I find the factor combinations of the number 168,575?

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 168,575, 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.

1 168,575
-1 -168,575

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 168,575.

Example:
1 x 168,575 = 168,575
and
-1 x -168,575 = 168,575
Notice both answers equal 168,575

With that explanation out of the way, let's continue. Next, we take the number 168,575 and divide it by 2:

168,575 ÷ 2 = 84,287.5

If the quotient is a whole number, then 2 and 84,287.5 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:

1 168,575
-1 -168,575

Now, we try dividing 168,575 by 3:

168,575 ÷ 3 = 56,191.6667

If the quotient is a whole number, then 3 and 56,191.6667 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:

1 168,575
-1 -168,575

Let's try dividing by 4:

168,575 ÷ 4 = 42,143.75

If the quotient is a whole number, then 4 and 42,143.75 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:

1 168,575
-1 168,575
Keep dividing by the next highest number until you cannot divide anymore.

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

151125552756133,0656,74315,32533,715168,575
