How do I find the factors or divisors of the number 218,720?

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 218,720, 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.

1 218,720

Next, we take the number 218,720 and divide it by 2.

In this case, 218,720 ÷ 2 = 109,360

If the quotient is a whole number, then 2 and 109,360 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 109,360 218,720

Now, we try dividing 218,720 by 3.

218,720 ÷ 3 = 72,906.6667

If the quotient is a whole number, then 3 and 72,906.6667 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 2 109,360 218,720

Let's try dividing by 4.

218,720 ÷ 4 = 54,680

If the quotient is a whole number, then 4 and 54,680 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 54,680 109,360 218,720

We keep dividing by the next largest number, in this case the number 5. If the quotient of 218,720 ÷ 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:

124581016203240801601,3672,7345,4686,83510,93613,67021,87227,34043,74454,680109,360218,720

All of the numbers in the table above can be evenly divided into the number 218,720.

Finally, for your reference, here are all of the divisor combinations of the number 218,720:
