How do I find the factors or divisors of the number 1,399,320?

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 1,399,320, 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 1,399,320

Next, we take the number 1,399,320 and divide it by 2.

In this case, 1,399,320 ÷ 2 = 699,660

If the quotient is a whole number, then 2 and 699,660 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 699,660 1,399,320

Now, we try dividing 1,399,320 by 3.

1,399,320 ÷ 3 = 466,440

If the quotient is a whole number, then 3 and 466,440 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 3 466,440 699,660 1,399,320

Let's try dividing by 4.

1,399,320 ÷ 4 = 349,830

If the quotient is a whole number, then 4 and 349,830 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 4 349,830 466,440 699,660 1,399,320

We keep dividing by the next largest number, in this case the number 5. If the quotient of 1,399,320 ÷ 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:
