<jupyter_start><jupyter_text>GCD Given n numbers, find the greatest common denominator between them. For example, given the numbers [42, 56, 14], return 14. Answer Logic- We're going to have to use recursion- A while loop can also work given the nature of the problem- This dual assignment pattern is powerful and useful ... a, b = b, a%b makes sense<jupyter_code>def gcd_(a,b): 
    while b: 
        a, b = b, a%b
    return a
gcd_(42, 14)
gcd_(14, 42)<jupyter_output><empty_output>
