Simplify Square Root of 3924

Here we will show you two methods that you can use to simplify the square root of 3924. In other words, we will show you how to find the square root of 3924 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.

√3924 = A√B

Greatest Perfect Square Factor Method
The Greatest Perfect Square Factor Method uses the greatest perfect square factor of 3924 to simplify the square root of 3924. 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 3924. The factors of 3924 are 1, 2, 3, 4, 6, 9, 12, 18, 36, 109, 218, 327, 436, 654, 981, 1308, 1962, and 3924. Furthermore, the greatest perfect square on this list is 36 and the square root of 36 is 6. Therefore, A equals 6.

B = Calculate 3924 divided by the greatest perfect square from the list of all factors of 3924. We determined above that the greatest perfect square from the list of all factors of 3924 is 36. Furthermore, 3924 divided by 36 is 109, therefore B equals 109.

Now we have A and B and can get our answer to 3924 in its simplest radical form as follows:

√3924 = A√B

√3924 = 6√109

Double Prime Factor Method
The Double Prime Factor Method uses the prime factors of 3924 to simplify the square root of 3924 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 3924 and then take the square root of that product. The prime factors that multiply together to make 3924 are 2 x 2 x 3 x 3 x 109. When we strip out the pairs only, we get 2 x 2 x 3 x 3 = 36 and the square root of 36 is 6. Therefore, A equals 6.

B = Divide 3924 by the number (A) squared. 6 squared is 36 and 3924 divided by 36 is 109. Therefore, B equals 109.

Once again we have A and B and can get our answer to 3924 in its simplest radical form as follows:

√3924 = A√B

√3924 = 6√109
