How do I find the factors or divisors of the number 310,538,420?

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 310,538,420, 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.

1 310,538,420

Next, we take the number 310,538,420 and divide it by 2.

In this case, 310,538,420 ÷ 2 = 155,269,210

If the quotient is a whole number, then 2 and 155,269,210 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 155,269,210 310,538,420

Now, we try dividing 310,538,420 by 3.

310,538,420 ÷ 3 = 103,512,806.6667

If the quotient is a whole number, then 3 and 103,512,806.6667 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 2 155,269,210 310,538,420

Let's try dividing by 4.

310,538,420 ÷ 4 = 77,634,605

If the quotient is a whole number, then 4 and 77,634,605 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 77,634,605 155,269,210 310,538,420

We keep dividing by the next largest number, in this case the number 5. If the quotient of 310,538,420 ÷ 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:
