How do I find the factor combinations of the number 56,151,011?

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 56,151,011, 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 56,151,011
-1 -56,151,011

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 56,151,011.

Example:
1 x 56,151,011 = 56,151,011
and
-1 x -56,151,011 = 56,151,011
Notice both answers equal 56,151,011

With that explanation out of the way, let's continue. Next, we take the number 56,151,011 and divide it by 2:

56,151,011 ÷ 2 = 28,075,505.5

If the quotient is a whole number, then 2 and 28,075,505.5 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 56,151,011
-1 -56,151,011

Now, we try dividing 56,151,011 by 3:

56,151,011 ÷ 3 = 18,717,003.6667

If the quotient is a whole number, then 3 and 18,717,003.6667 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 56,151,011
-1 -56,151,011

Let's try dividing by 4:

56,151,011 ÷ 4 = 14,037,752.75

If the quotient is a whole number, then 4 and 14,037,752.75 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 56,151,011
-1 56,151,011
Keep dividing by the next highest number until you cannot divide anymore.

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

17491511,0577,3997,58953,123371,8611,145,9398,021,57356,151,011
