Simplify Square Root of 20175

Here we will show you two methods that you can use to simplify the square root of 20175. In other words, we will show you how to find the square root of 20175 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.

√20175 = A√B

Greatest Perfect Square Factor Method
The Greatest Perfect Square Factor Method uses the greatest perfect square factor of 20175 to simplify the square root of 20175. 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 20175. The factors of 20175 are 1, 3, 5, 15, 25, 75, 269, 807, 1345, 4035, 6725, and 20175. Furthermore, the greatest perfect square on this list is 25 and the square root of 25 is 5. Therefore, A equals 5.

B = Calculate 20175 divided by the greatest perfect square from the list of all factors of 20175. We determined above that the greatest perfect square from the list of all factors of 20175 is 25. Furthermore, 20175 divided by 25 is 807, therefore B equals 807.

Now we have A and B and can get our answer to 20175 in its simplest radical form as follows:

√20175 = A√B

√20175 = 5√807

Double Prime Factor Method
The Double Prime Factor Method uses the prime factors of 20175 to simplify the square root of 20175 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 20175 and then take the square root of that product. The prime factors that multiply together to make 20175 are 3 x 5 x 5 x 269. When we strip out the pairs only, we get 5 x 5 = 25 and the square root of 25 is 5. Therefore, A equals 5.

B = Divide 20175 by the number (A) squared. 5 squared is 25 and 20175 divided by 25 is 807. Therefore, B equals 807.

Once again we have A and B and can get our answer to 20175 in its simplest radical form as follows:

√20175 = A√B

√20175 = 5√807
