Problem 56553. Easy Sequences 81: Fibonacci Radicals

The radical of a positive integer x is defined as the product of the distinct prime numbers dividing x. For example, the distinct prime factors of is , therefore the radical of is . Similarly, the radicals of , and are , 5 and , respectively. The number1is considered to be the radical of itself.
For a given index n, if is the n-th Fibonacci number ( and for ), write a function R(n), that calculates the radical of .
For example, if then , therefore R(12) = 2 * 3 = 6.
And, for , , therefore R(24) = 2 * 3 * 7 * 23 = 966.
Since output can be large, please present R(n) as a string (double quotes) array of digits.
