How do I find the factors or divisors of the number 407,440?

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 407,440, 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.

1 407,440

Next, we take the number 407,440 and divide it by 2.

In this case, 407,440 ÷ 2 = 203,720

If the quotient is a whole number, then 2 and 203,720 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 203,720 407,440

Now, we try dividing 407,440 by 3.

407,440 ÷ 3 = 135,813.3333

If the quotient is a whole number, then 3 and 135,813.3333 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 2 203,720 407,440

Let's try dividing by 4.

407,440 ÷ 4 = 101,860

If the quotient is a whole number, then 4 and 101,860 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 4 101,860 203,720 407,440

We keep dividing by the next largest number, in this case the number 5. If the quotient of 407,440 ÷ 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:
