Simplify Square Root of 20208

Here we will show you two methods that you can use to simplify the square root of 20208. In other words, we will show you how to find the square root of 20208 in its simplest radical form using two different methods.

To be more specific, we have created an illustration below showing what we want to calculate. Our goal is to make "A" outside the radical (√) as large as possible, and "B" inside the radical (√) as small as possible.

√20208 = A√B

Greatest Perfect Square Factor Method
The Greatest Perfect Square Factor Method uses the greatest perfect square factor of 20208 to simplify the square root of 20208. This is how to calculate A and B using this method:

A = Calculate the square root of the greatest perfect square from the list of all factors of 20208. The factors of 20208 are 1, 2, 3, 4, 6, 8, 12, 16, 24, 48, 421, 842, 1263, 1684, 2526, 3368, 5052, 6736, 10104, and 20208. Furthermore, the greatest perfect square on this list is 16 and the square root of 16 is 4. Therefore, A equals 4.

B = Calculate 20208 divided by the greatest perfect square from the list of all factors of 20208. We determined above that the greatest perfect square from the list of all factors of 20208 is 16. Furthermore, 20208 divided by 16 is 1263, therefore B equals 1263.

Now we have A and B and can get our answer to 20208 in its simplest radical form as follows:

√20208 = A√B

√20208 = 4√1263

Double Prime Factor Method
The Double Prime Factor Method uses the prime factors of 20208 to simplify the square root of 20208 to its simplest form possible. This is how to calculate A and B using this method:

A = Multiply all the double prime factors (pairs) of 20208 and then take the square root of that product. The prime factors that multiply together to make 20208 are 2 x 2 x 2 x 2 x 3 x 421. When we strip out the pairs only, we get 2 x 2 x 2 x 2 = 16 and the square root of 16 is 4. Therefore, A equals 4.

B = Divide 20208 by the number (A) squared. 4 squared is 16 and 20208 divided by 16 is 1263. Therefore, B equals 1263.

Once again we have A and B and can get our answer to 20208 in its simplest radical form as follows:

√20208 = A√B

√20208 = 4√1263
