Simplify Square Root of 17955




Here we will show you two methods that you can use to simplify the square root of 17955. In other words, we will show you how to find the square root of 17955 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.

17955 = A√B




Greatest Perfect Square Factor Method
The Greatest Perfect Square Factor Method uses the greatest perfect square factor of 17955 to simplify the square root of 17955. 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 17955. The factors of 17955 are 1, 3, 5, 7, 9, 15, 19, 21, 27, 35, 45, 57, 63, 95, 105, 133, 135, 171, 189, 285, 315, 399, 513, 665, 855, 945, 1197, 1995, 2565, 3591, 5985, and 17955. Furthermore, the greatest perfect square on this list is 9 and the square root of 9 is 3. Therefore, A equals 3.

B = Calculate 17955 divided by the greatest perfect square from the list of all factors of 17955. We determined above that the greatest perfect square from the list of all factors of 17955 is 9. Furthermore, 17955 divided by 9 is 1995, therefore B equals 1995.

Now we have A and B and can get our answer to 17955 in its simplest radical form as follows:

17955 = A√B

17955 = 3√1995




Double Prime Factor Method
The Double Prime Factor Method uses the prime factors of 17955 to simplify the square root of 17955 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 17955 and then take the square root of that product. The prime factors that multiply together to make 17955 are 3 x 3 x 3 x 5 x 7 x 19. 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 17955 by the number (A) squared. 3 squared is 9 and 17955 divided by 9 is 1995. Therefore, B equals 1995.

Once again we have A and B and can get our answer to 17955 in its simplest radical form as follows:

17955 = A√B

17955 = 3√1995
