How do I find the factor combinations of the number 56,131,063?

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 56,131,063, 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 56,131,063
-1 -56,131,063

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 56,131,063.

Example:
1 x 56,131,063 = 56,131,063
and
-1 x -56,131,063 = 56,131,063
Notice both answers equal 56,131,063

With that explanation out of the way, let's continue. Next, we take the number 56,131,063 and divide it by 2:

56,131,063 ÷ 2 = 28,065,531.5

If the quotient is a whole number, then 2 and 28,065,531.5 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 56,131,063
-1 -56,131,063

Now, we try dividing 56,131,063 by 3:

56,131,063 ÷ 3 = 18,710,354.3333

If the quotient is a whole number, then 3 and 18,710,354.3333 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 56,131,063
-1 -56,131,063

Let's try dividing by 4:

56,131,063 ÷ 4 = 14,032,765.75

If the quotient is a whole number, then 4 and 14,032,765.75 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 56,131,063
-1 56,131,063
Keep dividing by the next highest number until you cannot divide anymore.

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

1232,440,48156,131,063
-1-23-2,440,481-56,131,063
