How do I find the factors or divisors of the number 20,195,808?

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 20,195,808, 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 20,195,808

Next, we take the number 20,195,808 and divide it by 2.

In this case, 20,195,808 ÷ 2 = 10,097,904

If the quotient is a whole number, then 2 and 10,097,904 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 10,097,904 20,195,808

Now, we try dividing 20,195,808 by 3.

20,195,808 ÷ 3 = 6,731,936

If the quotient is a whole number, then 3 and 6,731,936 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 3 6,731,936 10,097,904 20,195,808

Let's try dividing by 4.

20,195,808 ÷ 4 = 5,048,952

If the quotient is a whole number, then 4 and 5,048,952 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 3 4 5,048,952 6,731,936 10,097,904 20,195,808

We keep dividing by the next largest number, in this case the number 5. If the quotient of 20,195,808 ÷ 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:

123468121624324871961422132844265688521,1361,7042,2722,9633,4085,9266,8168,88911,85217,77823,70435,55647,40871,11294,816142,224210,373284,448420,746631,119841,4921,262,2381,682,9842,524,4763,365,9685,048,9526,731,93610,097,90420,195,808
