Q: What are the factor combinations of the number 487,692?

How do I find the factor combinations of the number 487,692?

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 487,692, 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		487,692
-1		-487,692

With that explanation out of the way, let's continue. Next, we take the number 487,692 and divide it by 2:

487,692 ÷ 2 = 243,846

If the quotient is a whole number, then 2 and 243,846 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!

Here is what our table should look like at this step:

Now, we try dividing 487,692 by 3:

487,692 ÷ 3 = 162,564

If the quotient is a whole number, then 3 and 162,564 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!

Here is what our table should look like at this step:

Let's try dividing by 4:

487,692 ÷ 4 = 121,923

If the quotient is a whole number, then 4 and 121,923 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!

Here is what our table should look like at this step:

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