Simplify Square Root of 76928

Here we will show you two methods that you can use to simplify the square root of 76928. In other words, we will show you how to find the square root of 76928 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.

√76928 = A√B

Greatest Perfect Square Factor Method
The Greatest Perfect Square Factor Method uses the greatest perfect square factor of 76928 to simplify the square root of 76928. 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 76928. The factors of 76928 are 1, 2, 4, 8, 16, 32, 64, 128, 601, 1202, 2404, 4808, 9616, 19232, 38464, and 76928. Furthermore, the greatest perfect square on this list is 64 and the square root of 64 is 8. Therefore, A equals 8.

B = Calculate 76928 divided by the greatest perfect square from the list of all factors of 76928. We determined above that the greatest perfect square from the list of all factors of 76928 is 64. Furthermore, 76928 divided by 64 is 1202, therefore B equals 1202.

Now we have A and B and can get our answer to 76928 in its simplest radical form as follows:

√76928 = A√B

√76928 = 8√1202

Double Prime Factor Method
The Double Prime Factor Method uses the prime factors of 76928 to simplify the square root of 76928 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 76928 and then take the square root of that product. The prime factors that multiply together to make 76928 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 601. When we strip out the pairs only, we get 2 x 2 x 2 x 2 x 2 x 2 = 64 and the square root of 64 is 8. Therefore, A equals 8.

B = Divide 76928 by the number (A) squared. 8 squared is 64 and 76928 divided by 64 is 1202. Therefore, B equals 1202.

Once again we have A and B and can get our answer to 76928 in its simplest radical form as follows:

√76928 = A√B

√76928 = 8√1202
