Simplify Square Root of 17919

Here we will show you two methods that you can use to simplify the square root of 17919. In other words, we will show you how to find the square root of 17919 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.

√17919 = A√B

Greatest Perfect Square Factor Method
The Greatest Perfect Square Factor Method uses the greatest perfect square factor of 17919 to simplify the square root of 17919. 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 17919. The factors of 17919 are 1, 3, 9, 11, 33, 99, 181, 543, 1629, 1991, 5973, and 17919. Furthermore, the greatest perfect square on this list is 9 and the square root of 9 is 3. Therefore, A equals 3.

B = Calculate 17919 divided by the greatest perfect square from the list of all factors of 17919. We determined above that the greatest perfect square from the list of all factors of 17919 is 9. Furthermore, 17919 divided by 9 is 1991, therefore B equals 1991.

Now we have A and B and can get our answer to 17919 in its simplest radical form as follows:

√17919 = A√B

√17919 = 3√1991

Double Prime Factor Method
The Double Prime Factor Method uses the prime factors of 17919 to simplify the square root of 17919 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 17919 and then take the square root of that product. The prime factors that multiply together to make 17919 are 3 x 3 x 11 x 181. When we strip out the pairs only, we get 3 x 3 = 9 and the square root of 9 is 3. Therefore, A equals 3.

B = Divide 17919 by the number (A) squared. 3 squared is 9 and 17919 divided by 9 is 1991. Therefore, B equals 1991.

Once again we have A and B and can get our answer to 17919 in its simplest radical form as follows:

√17919 = A√B

√17919 = 3√1991
