Simplify Square Root of 39240

Here we will show you two methods that you can use to simplify the square root of 39240. In other words, we will show you how to find the square root of 39240 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.

√39240 = A√B

Greatest Perfect Square Factor Method
The Greatest Perfect Square Factor Method uses the greatest perfect square factor of 39240 to simplify the square root of 39240. 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 39240. The factors of 39240 are 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 109, 120, 180, 218, 327, 360, 436, 545, 654, 872, 981, 1090, 1308, 1635, 1962, 2180, 2616, 3270, 3924, 4360, 4905, 6540, 7848, 9810, 13080, 19620, and 39240. Furthermore, the greatest perfect square on this list is 36 and the square root of 36 is 6. Therefore, A equals 6.

B = Calculate 39240 divided by the greatest perfect square from the list of all factors of 39240. We determined above that the greatest perfect square from the list of all factors of 39240 is 36. Furthermore, 39240 divided by 36 is 1090, therefore B equals 1090.

Now we have A and B and can get our answer to 39240 in its simplest radical form as follows:

√39240 = A√B

√39240 = 6√1090

Double Prime Factor Method
The Double Prime Factor Method uses the prime factors of 39240 to simplify the square root of 39240 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 39240 and then take the square root of that product. The prime factors that multiply together to make 39240 are 2 x 2 x 2 x 3 x 3 x 5 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 39240 by the number (A) squared. 6 squared is 36 and 39240 divided by 36 is 1090. Therefore, B equals 1090.

Once again we have A and B and can get our answer to 39240 in its simplest radical form as follows:

√39240 = A√B

√39240 = 6√1090
