Q: What are the factor combinations of the number 547,743,285?

How do I find the factor combinations of the number 547,743,285?

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 547,743,285, 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		547,743,285
-1		-547,743,285

With that explanation out of the way, let's continue. Next, we take the number 547,743,285 and divide it by 2:

547,743,285 ÷ 2 = 273,871,642.5

If the quotient is a whole number, then 2 and 273,871,642.5 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:

Now, we try dividing 547,743,285 by 3:

547,743,285 ÷ 3 = 182,581,095

If the quotient is a whole number, then 3 and 182,581,095 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:

547,743,285 ÷ 4 = 136,935,821.25

If the quotient is a whole number, then 4 and 136,935,821.25 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:

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