How do I find the factors or divisors of the number 216,426,540?

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 216,426,540, 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.

1 216,426,540

Next, we take the number 216,426,540 and divide it by 2.

In this case, 216,426,540 ÷ 2 = 108,213,270

If the quotient is a whole number, then 2 and 108,213,270 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 108,213,270 216,426,540

Now, we try dividing 216,426,540 by 3.

216,426,540 ÷ 3 = 72,142,180

If the quotient is a whole number, then 3 and 72,142,180 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 72,142,180 108,213,270 216,426,540

Let's try dividing by 4.

216,426,540 ÷ 4 = 54,106,635

If the quotient is a whole number, then 4 and 54,106,635 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 54,106,635 72,142,180 108,213,270 216,426,540

We keep dividing by the next largest number, in this case the number 5. If the quotient of 216,426,540 ÷ 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.
