Simplify Square Root of 440

Here we will show you two methods that you can use to simplify the square root of 440. In other words, we will show you how to find the square root of 440 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.

√440 = A√B

Greatest Perfect Square Factor Method
The Greatest Perfect Square Factor Method uses the greatest perfect square factor of 440 to simplify the square root of 440. 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 440. The factors of 440 are 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, and 440. Furthermore, the greatest perfect square on this list is 4 and the square root of 4 is 2. Therefore, A equals 2.

B = Calculate 440 divided by the greatest perfect square from the list of all factors of 440. We determined above that the greatest perfect square from the list of all factors of 440 is 4. Furthermore, 440 divided by 4 is 110, therefore B equals 110.

Now we have A and B and can get our answer to 440 in its simplest radical form as follows:

√440 = A√B

√440 = 2√110

Double Prime Factor Method
The Double Prime Factor Method uses the prime factors of 440 to simplify the square root of 440 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 440 and then take the square root of that product. The prime factors that multiply together to make 440 are 2 x 2 x 2 x 5 x 11. When we strip out the pairs only, we get 2 x 2 = 4 and the square root of 4 is 2. Therefore, A equals 2.

B = Divide 440 by the number (A) squared. 2 squared is 4 and 440 divided by 4 is 110. Therefore, B equals 110.

Once again we have A and B and can get our answer to 440 in its simplest radical form as follows:

√440 = A√B

√440 = 2√110
