How do I find the factors or divisors of the number 306,480?

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 306,480, 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.

1 306,480

Next, we take the number 306,480 and divide it by 2.

In this case, 306,480 ÷ 2 = 153,240

If the quotient is a whole number, then 2 and 153,240 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 153,240 306,480

Now, we try dividing 306,480 by 3.

306,480 ÷ 3 = 102,160

If the quotient is a whole number, then 3 and 102,160 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 3 102,160 153,240 306,480

Let's try dividing by 4.

306,480 ÷ 4 = 76,620

If the quotient is a whole number, then 4 and 76,620 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 76,620 102,160 153,240 306,480

We keep dividing by the next largest number, in this case the number 5. If the quotient of 306,480 ÷ 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:
