How do I find the factors or divisors of the number 215,904?

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 215,904, 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.

1 215,904

Next, we take the number 215,904 and divide it by 2.

In this case, 215,904 ÷ 2 = 107,952

If the quotient is a whole number, then 2 and 107,952 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 107,952 215,904

Now, we try dividing 215,904 by 3.

215,904 ÷ 3 = 71,968

If the quotient is a whole number, then 3 and 71,968 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 71,968 107,952 215,904

Let's try dividing by 4.

215,904 ÷ 4 = 53,976

If the quotient is a whole number, then 4 and 53,976 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 53,976 71,968 107,952 215,904

We keep dividing by the next largest number, in this case the number 5. If the quotient of 215,904 ÷ 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:

12346812131624263239485278961041561732083123464165196246921,0381,2481,3842,0762,2492,7684,1524,4985,5366,7478,3048,99613,49416,60817,99226,98835,98453,97671,968107,952215,904

All of the numbers in the table above can be evenly divided into the number 215,904.
