Simplify Square Root of 77450

Here we will show you two methods that you can use to simplify the square root of 77450. In other words, we will show you how to find the square root of 77450 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.

√77450 = A√B

Greatest Perfect Square Factor Method
The Greatest Perfect Square Factor Method uses the greatest perfect square factor of 77450 to simplify the square root of 77450. 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 77450. The factors of 77450 are 1, 2, 5, 10, 25, 50, 1549, 3098, 7745, 15490, 38725, and 77450. Furthermore, the greatest perfect square on this list is 25 and the square root of 25 is 5. Therefore, A equals 5.

B = Calculate 77450 divided by the greatest perfect square from the list of all factors of 77450. We determined above that the greatest perfect square from the list of all factors of 77450 is 25. Furthermore, 77450 divided by 25 is 3098, therefore B equals 3098.

Now we have A and B and can get our answer to 77450 in its simplest radical form as follows:

√77450 = A√B

√77450 = 5√3098

Double Prime Factor Method
The Double Prime Factor Method uses the prime factors of 77450 to simplify the square root of 77450 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 77450 and then take the square root of that product. The prime factors that multiply together to make 77450 are 2 x 5 x 5 x 1549. When we strip out the pairs only, we get 5 x 5 = 25 and the square root of 25 is 5. Therefore, A equals 5.

B = Divide 77450 by the number (A) squared. 5 squared is 25 and 77450 divided by 25 is 3098. Therefore, B equals 3098.

Once again we have A and B and can get our answer to 77450 in its simplest radical form as follows:

√77450 = A√B

√77450 = 5√3098
