How do I find the factors or divisors of the number 201,172,164?

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 201,172,164, 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.

1 201,172,164

Next, we take the number 201,172,164 and divide it by 2.

In this case, 201,172,164 ÷ 2 = 100,586,082

If the quotient is a whole number, then 2 and 100,586,082 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 100,586,082 201,172,164

Now, we try dividing 201,172,164 by 3.

201,172,164 ÷ 3 = 67,057,388

If the quotient is a whole number, then 3 and 67,057,388 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 67,057,388 100,586,082 201,172,164

Let's try dividing by 4.

201,172,164 ÷ 4 = 50,293,041

If the quotient is a whole number, then 4 and 50,293,041 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 50,293,041 67,057,388 100,586,082 201,172,164

We keep dividing by the next largest number, in this case the number 5. If the quotient of 201,172,164 ÷ 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:

123461216,764,34733,528,69450,293,04167,057,388100,586,082201,172,164

All of the numbers in the table above can be evenly divided into the number 201,172,164.
