Simplify Square Root of 28188

Here we will show you two methods that you can use to simplify the square root of 28188. In other words, we will show you how to find the square root of 28188 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.

√28188 = A√B

Greatest Perfect Square Factor Method
The Greatest Perfect Square Factor Method uses the greatest perfect square factor of 28188 to simplify the square root of 28188. 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 28188. The factors of 28188 are 1, 2, 3, 4, 6, 9, 12, 18, 27, 29, 36, 54, 58, 81, 87, 108, 116, 162, 174, 243, 261, 324, 348, 486, 522, 783, 972, 1044, 1566, 2349, 3132, 4698, 7047, 9396, 14094, and 28188. Furthermore, the greatest perfect square on this list is 324 and the square root of 324 is 18. Therefore, A equals 18.

B = Calculate 28188 divided by the greatest perfect square from the list of all factors of 28188. We determined above that the greatest perfect square from the list of all factors of 28188 is 324. Furthermore, 28188 divided by 324 is 87, therefore B equals 87.

Now we have A and B and can get our answer to 28188 in its simplest radical form as follows:

√28188 = A√B

√28188 = 18√87

Double Prime Factor Method
The Double Prime Factor Method uses the prime factors of 28188 to simplify the square root of 28188 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 28188 and then take the square root of that product. The prime factors that multiply together to make 28188 are 2 x 2 x 3 x 3 x 3 x 3 x 3 x 29. When we strip out the pairs only, we get 2 x 2 x 3 x 3 x 3 x 3 = 324 and the square root of 324 is 18. Therefore, A equals 18.

B = Divide 28188 by the number (A) squared. 18 squared is 324 and 28188 divided by 324 is 87. Therefore, B equals 87.

Once again we have A and B and can get our answer to 28188 in its simplest radical form as follows:

√28188 = A√B

√28188 = 18√87
