Simplify Square Root of 21957

What is the square root of 21957 in its simplest radical form? 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.

√21957 = A√B

Unfortunately, the square root of 21957 cannot be simplified. Thus, here is the answer to the square root of 21957 in its simplest form:

√ 21957 = √ 21957

Here are two different methods we used to determine why the square root of 21957 cannot be simplified.

1) To be able to simplify the square root of 21957, one of the factors of 21957 other than 1 must be a perfect square. The factors of 21957 are 1, 3, 13, 39, 563, 1689, 7319, and 21957. Since none of these factors are perfect squares, the square root of 21957 cannot be simplified.

2) To be able to simplify the square root of 21957, all the prime factors of 21957 cannot be unique. When we did prime factorization of 21957, we found that 3 x 13 x 563 equals 21957. Since all the prime factors are unique, the square root of 21957 cannot be simplified.
