Simplify Square Root of 19220

Here we will show you two methods that you can use to simplify the square root of 19220. In other words, we will show you how to find the square root of 19220 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.

√19220 = A√B

Greatest Perfect Square Factor Method
The Greatest Perfect Square Factor Method uses the greatest perfect square factor of 19220 to simplify the square root of 19220. 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 19220. The factors of 19220 are 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620, 961, 1922, 3844, 4805, 9610, and 19220. Furthermore, the greatest perfect square on this list is 3844 and the square root of 3844 is 62. Therefore, A equals 62.

B = Calculate 19220 divided by the greatest perfect square from the list of all factors of 19220. We determined above that the greatest perfect square from the list of all factors of 19220 is 3844. Furthermore, 19220 divided by 3844 is 5, therefore B equals 5.

Now we have A and B and can get our answer to 19220 in its simplest radical form as follows:

√19220 = A√B

√19220 = 62√5

Double Prime Factor Method
The Double Prime Factor Method uses the prime factors of 19220 to simplify the square root of 19220 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 19220 and then take the square root of that product. The prime factors that multiply together to make 19220 are 2 x 2 x 5 x 31 x 31. When we strip out the pairs only, we get 2 x 2 x 31 x 31 = 3844 and the square root of 3844 is 62. Therefore, A equals 62.

B = Divide 19220 by the number (A) squared. 62 squared is 3844 and 19220 divided by 3844 is 5. Therefore, B equals 5.

Once again we have A and B and can get our answer to 19220 in its simplest radical form as follows:

√19220 = A√B

√19220 = 62√5
