Simplify Square Root of 86416

Here we will show you two methods that you can use to simplify the square root of 86416. In other words, we will show you how to find the square root of 86416 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.

√86416 = A√B

Greatest Perfect Square Factor Method
The Greatest Perfect Square Factor Method uses the greatest perfect square factor of 86416 to simplify the square root of 86416. 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 86416. The factors of 86416 are 1, 2, 4, 8, 11, 16, 22, 44, 88, 176, 491, 982, 1964, 3928, 5401, 7856, 10802, 21604, 43208, and 86416. Furthermore, the greatest perfect square on this list is 16 and the square root of 16 is 4. Therefore, A equals 4.

B = Calculate 86416 divided by the greatest perfect square from the list of all factors of 86416. We determined above that the greatest perfect square from the list of all factors of 86416 is 16. Furthermore, 86416 divided by 16 is 5401, therefore B equals 5401.

Now we have A and B and can get our answer to 86416 in its simplest radical form as follows:

√86416 = A√B

√86416 = 4√5401

Double Prime Factor Method
The Double Prime Factor Method uses the prime factors of 86416 to simplify the square root of 86416 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 86416 and then take the square root of that product. The prime factors that multiply together to make 86416 are 2 x 2 x 2 x 2 x 11 x 491. When we strip out the pairs only, we get 2 x 2 x 2 x 2 = 16 and the square root of 16 is 4. Therefore, A equals 4.

B = Divide 86416 by the number (A) squared. 4 squared is 16 and 86416 divided by 16 is 5401. Therefore, B equals 5401.

Once again we have A and B and can get our answer to 86416 in its simplest radical form as follows:

√86416 = A√B

√86416 = 4√5401
