Problem 57839. Easy Sequences 104: One-line Code Challenge - GCDs of Sum of Consecutive Cubes

For a natural number, n, the function CC(n) is defined as follows:
In other words, CC(n) is the sum of cubes of all integers from 1 to n.
Given positive integers x and y, write a function that calculates the value of gcd(CC(x),CC(y)) . For example:
>> CC = @(n) sum((1:n).^3);
>> gcdCC = @(x,y) gcd(CC(x),CC(y));
>> gcdCC(5,10)
ans = 25
The following restrictions apply:
  • The function should only have one (1) line of code, excluding the function start line.
  • Semicolons (;) are considered end-of-line characters.
  • Please suppress the function end line. Keyword 'end' is not allowed.
  • Regular expressions are not allowed.
  • Only 'pure' matlab functions/commands are allowed (no java, no python).
