Simplify Square Root of 72208

Here we will show you two methods that you can use to simplify the square root of 72208. In other words, we will show you how to find the square root of 72208 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.

√72208 = A√B

Greatest Perfect Square Factor Method
The Greatest Perfect Square Factor Method uses the greatest perfect square factor of 72208 to simplify the square root of 72208. 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 72208. The factors of 72208 are 1, 2, 4, 8, 16, 4513, 9026, 18052, 36104, and 72208. Furthermore, the greatest perfect square on this list is 16 and the square root of 16 is 4. Therefore, A equals 4.

B = Calculate 72208 divided by the greatest perfect square from the list of all factors of 72208. We determined above that the greatest perfect square from the list of all factors of 72208 is 16. Furthermore, 72208 divided by 16 is 4513, therefore B equals 4513.

Now we have A and B and can get our answer to 72208 in its simplest radical form as follows:

√72208 = A√B

√72208 = 4√4513

Double Prime Factor Method
The Double Prime Factor Method uses the prime factors of 72208 to simplify the square root of 72208 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 72208 and then take the square root of that product. The prime factors that multiply together to make 72208 are 2 x 2 x 2 x 2 x 4513. 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 72208 by the number (A) squared. 4 squared is 16 and 72208 divided by 16 is 4513. Therefore, B equals 4513.

Once again we have A and B and can get our answer to 72208 in its simplest radical form as follows:

√72208 = A√B

√72208 = 4√4513
