How do I find the factors or divisors of the number 213,121,012?

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 213,121,012, 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.

1 213,121,012

Next, we take the number 213,121,012 and divide it by 2.

In this case, 213,121,012 ÷ 2 = 106,560,506

If the quotient is a whole number, then 2 and 106,560,506 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 106,560,506 213,121,012

Now, we try dividing 213,121,012 by 3.

213,121,012 ÷ 3 = 71,040,337.3333

If the quotient is a whole number, then 3 and 71,040,337.3333 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 2 106,560,506 213,121,012

Let's try dividing by 4.

213,121,012 ÷ 4 = 53,280,253

If the quotient is a whole number, then 4 and 53,280,253 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 53,280,253 106,560,506 213,121,012

We keep dividing by the next largest number, in this case the number 5. If the quotient of 213,121,012 ÷ 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:

1241326524,098,4818,196,96216,393,92453,280,253106,560,506213,121,012

All of the numbers in the table above can be evenly divided into the number 213,121,012.
