How do I find the factors or divisors of the number 55,138,016?

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 factors of larger numbers. To find the factors of the number 55,138,016, it is easiest to start from the outside in. Here's what we mean:

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.

1 55,138,016

Next, we take the number 55,138,016 and divide it by 2.

In this case, 55,138,016 ÷ 2 = 27,569,008

If the quotient is a whole number, then 2 and 27,569,008 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 27,569,008 55,138,016

Now, we try dividing 55,138,016 by 3.

55,138,016 ÷ 3 = 18,379,338.6667

If the quotient is a whole number, then 3 and 18,379,338.6667 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

Here is what our table should look like at this step:

1 2 27,569,008 55,138,016

Let's try dividing by 4.

55,138,016 ÷ 4 = 13,784,504

If the quotient is a whole number, then 4 and 13,784,504 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

Here is what our table should look like at this step:

1 2 4 13,784,504 27,569,008 55,138,016

We keep dividing by the next largest number, in this case the number 5. If the quotient of 55,138,016 ÷ 5 is a whole number, then 5 and your quotient are factors of the number.


Keep dividing by the next highest number until you cannot divide anymore.


What you will end up with is this table:

124816321,723,0633,446,1266,892,25213,784,50427,569,00855,138,016

All of the numbers in the table above can be evenly divided into the number 55,138,016.
