Simplify Square Root of 70768

Here we will show you two methods that you can use to simplify the square root of 70768. In other words, we will show you how to find the square root of 70768 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.

√70768 = A√B

Greatest Perfect Square Factor Method
The Greatest Perfect Square Factor Method uses the greatest perfect square factor of 70768 to simplify the square root of 70768. 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 70768. The factors of 70768 are 1, 2, 4, 8, 16, 4423, 8846, 17692, 35384, and 70768. Furthermore, the greatest perfect square on this list is 16 and the square root of 16 is 4. Therefore, A equals 4.

B = Calculate 70768 divided by the greatest perfect square from the list of all factors of 70768. We determined above that the greatest perfect square from the list of all factors of 70768 is 16. Furthermore, 70768 divided by 16 is 4423, therefore B equals 4423.

Now we have A and B and can get our answer to 70768 in its simplest radical form as follows:

√70768 = A√B

√70768 = 4√4423

Double Prime Factor Method
The Double Prime Factor Method uses the prime factors of 70768 to simplify the square root of 70768 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 70768 and then take the square root of that product. The prime factors that multiply together to make 70768 are 2 x 2 x 2 x 2 x 4423. 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 70768 by the number (A) squared. 4 squared is 16 and 70768 divided by 16 is 4423. Therefore, B equals 4423.

Once again we have A and B and can get our answer to 70768 in its simplest radical form as follows:

√70768 = A√B

√70768 = 4√4423
