Simplify Square Root of 27450

Here we will show you two methods that you can use to simplify the square root of 27450. In other words, we will show you how to find the square root of 27450 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.

√27450 = A√B

Greatest Perfect Square Factor Method
The Greatest Perfect Square Factor Method uses the greatest perfect square factor of 27450 to simplify the square root of 27450. 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 27450. The factors of 27450 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 61, 75, 90, 122, 150, 183, 225, 305, 366, 450, 549, 610, 915, 1098, 1525, 1830, 2745, 3050, 4575, 5490, 9150, 13725, and 27450. Furthermore, the greatest perfect square on this list is 225 and the square root of 225 is 15. Therefore, A equals 15.

B = Calculate 27450 divided by the greatest perfect square from the list of all factors of 27450. We determined above that the greatest perfect square from the list of all factors of 27450 is 225. Furthermore, 27450 divided by 225 is 122, therefore B equals 122.

Now we have A and B and can get our answer to 27450 in its simplest radical form as follows:

√27450 = A√B

√27450 = 15√122

Double Prime Factor Method
The Double Prime Factor Method uses the prime factors of 27450 to simplify the square root of 27450 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 27450 and then take the square root of that product. The prime factors that multiply together to make 27450 are 2 x 3 x 3 x 5 x 5 x 61. When we strip out the pairs only, we get 3 x 3 x 5 x 5 = 225 and the square root of 225 is 15. Therefore, A equals 15.

B = Divide 27450 by the number (A) squared. 15 squared is 225 and 27450 divided by 225 is 122. Therefore, B equals 122.

Once again we have A and B and can get our answer to 27450 in its simplest radical form as follows:

√27450 = A√B

√27450 = 15√122
