How do I find the factors or divisors of the number 1,380,960?

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 1,380,960, 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 1,380,960

Next, we take the number 1,380,960 and divide it by 2.

In this case, 1,380,960 ÷ 2 = 690,480

If the quotient is a whole number, then 2 and 690,480 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 690,480 1,380,960

Now, we try dividing 1,380,960 by 3.

1,380,960 ÷ 3 = 460,320

If the quotient is a whole number, then 3 and 460,320 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 3 460,320 690,480 1,380,960

Let's try dividing by 4.

1,380,960 ÷ 4 = 345,240

If the quotient is a whole number, then 4 and 345,240 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 4 345,240 460,320 690,480 1,380,960

We keep dividing by the next largest number, in this case the number 5. If the quotient of 1,380,960 ÷ 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:
