Simplify Square Root of 65808

Here we will show you two methods that you can use to simplify the square root of 65808. In other words, we will show you how to find the square root of 65808 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.

√65808 = A√B

Greatest Perfect Square Factor Method
The Greatest Perfect Square Factor Method uses the greatest perfect square factor of 65808 to simplify the square root of 65808. 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 65808. The factors of 65808 are 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144, 457, 914, 1371, 1828, 2742, 3656, 4113, 5484, 7312, 8226, 10968, 16452, 21936, 32904, and 65808. Furthermore, the greatest perfect square on this list is 144 and the square root of 144 is 12. Therefore, A equals 12.

B = Calculate 65808 divided by the greatest perfect square from the list of all factors of 65808. We determined above that the greatest perfect square from the list of all factors of 65808 is 144. Furthermore, 65808 divided by 144 is 457, therefore B equals 457.

Now we have A and B and can get our answer to 65808 in its simplest radical form as follows:

√65808 = A√B

√65808 = 12√457

Double Prime Factor Method
The Double Prime Factor Method uses the prime factors of 65808 to simplify the square root of 65808 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 65808 and then take the square root of that product. The prime factors that multiply together to make 65808 are 2 x 2 x 2 x 2 x 3 x 3 x 457. 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 65808 by the number (A) squared. 12 squared is 144 and 65808 divided by 144 is 457. Therefore, B equals 457.

Once again we have A and B and can get our answer to 65808 in its simplest radical form as follows:

√65808 = A√B

√65808 = 12√457
