How do I find the factors or divisors of the number 1,355,520?

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 1,355,520, 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 1,355,520

Next, we take the number 1,355,520 and divide it by 2.

In this case, 1,355,520 ÷ 2 = 677,760

If the quotient is a whole number, then 2 and 677,760 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 677,760 1,355,520

Now, we try dividing 1,355,520 by 3.

1,355,520 ÷ 3 = 451,840

If the quotient is a whole number, then 3 and 451,840 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 3 451,840 677,760 1,355,520

Let's try dividing by 4.

1,355,520 ÷ 4 = 338,880

If the quotient is a whole number, then 4 and 338,880 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 4 338,880 451,840 677,760 1,355,520

We keep dividing by the next largest number, in this case the number 5. If the quotient of 1,355,520 ÷ 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:
