How do I find the factors or divisors of the number 311,321,200?

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 311,321,200, 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.

1 311,321,200

Next, we take the number 311,321,200 and divide it by 2.

In this case, 311,321,200 ÷ 2 = 155,660,600

If the quotient is a whole number, then 2 and 155,660,600 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 155,660,600 311,321,200

Now, we try dividing 311,321,200 by 3.

311,321,200 ÷ 3 = 103,773,733.3333

If the quotient is a whole number, then 3 and 103,773,733.3333 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 2 155,660,600 311,321,200

Let's try dividing by 4.

311,321,200 ÷ 4 = 77,830,300

If the quotient is a whole number, then 4 and 77,830,300 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 77,830,300 155,660,600 311,321,200

We keep dividing by the next largest number, in this case the number 5. If the quotient of 311,321,200 ÷ 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:
