How do I find the factor combinations of the number 49,049?

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 49,049, 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 49,049
-1 -49,049

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 49,049.

Example:
1 x 49,049 = 49,049
and
-1 x -49,049 = 49,049
Notice both answers equal 49,049

With that explanation out of the way, let's continue. Next, we take the number 49,049 and divide it by 2:

49,049 ÷ 2 = 24,524.5

If the quotient is a whole number, then 2 and 24,524.5 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 49,049
-1 -49,049

Now, we try dividing 49,049 by 3:

49,049 ÷ 3 = 16,349.6667

If the quotient is a whole number, then 3 and 16,349.6667 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 49,049
-1 -49,049

Let's try dividing by 4:

49,049 ÷ 4 = 12,262.25

If the quotient is a whole number, then 4 and 12,262.25 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 49,049
-1 49,049
Keep dividing by the next highest number until you cannot divide anymore.

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

1711134977911433435396371,0013,7734,4597,00749,049
