Simplify Square Root of 20880

Here we will show you two methods that you can use to simplify the square root of 20880. In other words, we will show you how to find the square root of 20880 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.

√20880 = A√B

Greatest Perfect Square Factor Method
The Greatest Perfect Square Factor Method uses the greatest perfect square factor of 20880 to simplify the square root of 20880. 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 20880. The factors of 20880 are 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 29, 30, 36, 40, 45, 48, 58, 60, 72, 80, 87, 90, 116, 120, 144, 145, 174, 180, 232, 240, 261, 290, 348, 360, 435, 464, 522, 580, 696, 720, 870, 1044, 1160, 1305, 1392, 1740, 2088, 2320, 2610, 3480, 4176, 5220, 6960, 10440, and 20880. Furthermore, the greatest perfect square on this list is 144 and the square root of 144 is 12. Therefore, A equals 12.

B = Calculate 20880 divided by the greatest perfect square from the list of all factors of 20880. We determined above that the greatest perfect square from the list of all factors of 20880 is 144. Furthermore, 20880 divided by 144 is 145, therefore B equals 145.

Now we have A and B and can get our answer to 20880 in its simplest radical form as follows:

√20880 = A√B

√20880 = 12√145

Double Prime Factor Method
The Double Prime Factor Method uses the prime factors of 20880 to simplify the square root of 20880 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 20880 and then take the square root of that product. The prime factors that multiply together to make 20880 are 2 x 2 x 2 x 2 x 3 x 3 x 5 x 29. When we strip out the pairs only, we get 2 x 2 x 2 x 2 x 3 x 3 = 144 and the square root of 144 is 12. Therefore, A equals 12.

B = Divide 20880 by the number (A) squared. 12 squared is 144 and 20880 divided by 144 is 145. Therefore, B equals 145.

Once again we have A and B and can get our answer to 20880 in its simplest radical form as follows:

√20880 = A√B

√20880 = 12√145
