How do I find the factor combinations of the number 50,545,027?

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 50,545,027, 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 50,545,027
-1 -50,545,027

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 50,545,027.

Example:
1 x 50,545,027 = 50,545,027
and
-1 x -50,545,027 = 50,545,027
Notice both answers equal 50,545,027

With that explanation out of the way, let's continue. Next, we take the number 50,545,027 and divide it by 2:

50,545,027 ÷ 2 = 25,272,513.5

If the quotient is a whole number, then 2 and 25,272,513.5 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 50,545,027
-1 -50,545,027

Now, we try dividing 50,545,027 by 3:

50,545,027 ÷ 3 = 16,848,342.3333

If the quotient is a whole number, then 3 and 16,848,342.3333 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 50,545,027
-1 -50,545,027

Let's try dividing by 4:

50,545,027 ÷ 4 = 12,636,256.75

If the quotient is a whole number, then 4 and 12,636,256.75 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 50,545,027
-1 50,545,027
Keep dividing by the next highest number until you cannot divide anymore.

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