How do I find the factors or divisors of the number 12,885,480?

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 12,885,480, 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 12,885,480

Next, we take the number 12,885,480 and divide it by 2.

In this case, 12,885,480 ÷ 2 = 6,442,740

If the quotient is a whole number, then 2 and 6,442,740 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 6,442,740 12,885,480

Now, we try dividing 12,885,480 by 3.

12,885,480 ÷ 3 = 4,295,160

If the quotient is a whole number, then 3 and 4,295,160 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 4,295,160 6,442,740 12,885,480

Let's try dividing by 4.

12,885,480 ÷ 4 = 3,221,370

If the quotient is a whole number, then 4 and 3,221,370 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 3,221,370 4,295,160 6,442,740 12,885,480

We keep dividing by the next largest number, in this case the number 5. If the quotient of 12,885,480 ÷ 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:
