How do I find the factor combinations of the number 534,132,049?

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 534,132,049, 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.

1 534,132,049
-1 -534,132,049

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 534,132,049.

Example:
1 x 534,132,049 = 534,132,049
and
-1 x -534,132,049 = 534,132,049
Notice both answers equal 534,132,049

With that explanation out of the way, let's continue. Next, we take the number 534,132,049 and divide it by 2:

534,132,049 ÷ 2 = 267,066,024.5

If the quotient is a whole number, then 2 and 267,066,024.5 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:

1 534,132,049
-1 -534,132,049

Now, we try dividing 534,132,049 by 3:

534,132,049 ÷ 3 = 178,044,016.3333

If the quotient is a whole number, then 3 and 178,044,016.3333 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:

1 534,132,049
-1 -534,132,049

Let's try dividing by 4:

534,132,049 ÷ 4 = 133,533,012.25

If the quotient is a whole number, then 4 and 133,533,012.25 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:

1 534,132,049
-1 534,132,049
Keep dividing by the next highest number until you cannot divide anymore.

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

1112692,959180,5111,985,62148,557,459534,132,049
