Simplify Square Root of 77355

Here we will show you two methods that you can use to simplify the square root of 77355. In other words, we will show you how to find the square root of 77355 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.

√77355 = A√B

Greatest Perfect Square Factor Method
The Greatest Perfect Square Factor Method uses the greatest perfect square factor of 77355 to simplify the square root of 77355. 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 77355. The factors of 77355 are 1, 3, 5, 9, 15, 27, 45, 81, 135, 191, 405, 573, 955, 1719, 2865, 5157, 8595, 15471, 25785, and 77355. Furthermore, the greatest perfect square on this list is 81 and the square root of 81 is 9. Therefore, A equals 9.

B = Calculate 77355 divided by the greatest perfect square from the list of all factors of 77355. We determined above that the greatest perfect square from the list of all factors of 77355 is 81. Furthermore, 77355 divided by 81 is 955, therefore B equals 955.

Now we have A and B and can get our answer to 77355 in its simplest radical form as follows:

√77355 = A√B

√77355 = 9√955

Double Prime Factor Method
The Double Prime Factor Method uses the prime factors of 77355 to simplify the square root of 77355 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 77355 and then take the square root of that product. The prime factors that multiply together to make 77355 are 3 x 3 x 3 x 3 x 5 x 191. When we strip out the pairs only, we get 3 x 3 x 3 x 3 = 81 and the square root of 81 is 9. Therefore, A equals 9.

B = Divide 77355 by the number (A) squared. 9 squared is 81 and 77355 divided by 81 is 955. Therefore, B equals 955.

Once again we have A and B and can get our answer to 77355 in its simplest radical form as follows:

√77355 = A√B

√77355 = 9√955
