How do I find the factor combinations of the number 152,383?

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 152,383, 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.

1 152,383
-1 -152,383

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 152,383.

Example:
1 x 152,383 = 152,383
and
-1 x -152,383 = 152,383
Notice both answers equal 152,383

With that explanation out of the way, let's continue. Next, we take the number 152,383 and divide it by 2:

152,383 ÷ 2 = 76,191.5

If the quotient is a whole number, then 2 and 76,191.5 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:

1 152,383
-1 -152,383

Now, we try dividing 152,383 by 3:

152,383 ÷ 3 = 50,794.3333

If the quotient is a whole number, then 3 and 50,794.3333 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:

1 152,383
-1 -152,383

Let's try dividing by 4:

152,383 ÷ 4 = 38,095.75

If the quotient is a whole number, then 4 and 38,095.75 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:

1 152,383
-1 152,383
Keep dividing by the next highest number until you cannot divide anymore.

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

1711771,97913,85321,769152,383
-1-7-11-77-1,979-13,853-21,769-152,383
