The GCD of given numbers is 1.
Step 1 : Find prime factorization of each number.
$$\begin{aligned}2 =& 2\\[8pt]5 =& 5\\[8pt]2 =& 2\\[8pt]4 =& 2\cdot2\\[8pt]3 =& 3\\[8pt]2 =& 2\\[8pt]3 =& 3\\[8pt]3 =& 3\\[8pt]2 =& 2\\[8pt]5 =& 5\\[8pt]2 =& 2\\[8pt]4 =& 2\cdot2\\[8pt]2 =& 2\\[8pt]3 =& 3\\[8pt]2 =& 2\\[8pt]2 =& 2\\[8pt]4 =& 2\cdot2\\[8pt]4 =& 2\cdot2\\[8pt]\end{aligned}$$(view steps on how to factor 2, 5, 2, 4, 3, 2, 3, 3, 2, 5, 2, 4, 2, 3, 2, 2, 4 and 4. )
Step 2 : Put a box around factors that are common for all numbers:
$$\begin{aligned}2 =& 2\\[8pt]5 =& 5\\[8pt]2 =& 2\\[8pt]4 =& 2\cdot2\\[8pt]3 =& 3\\[8pt]2 =& 2\\[8pt]3 =& 3\\[8pt]3 =& 3\\[8pt]2 =& 2\\[8pt]5 =& 5\\[8pt]2 =& 2\\[8pt]4 =& 2\cdot2\\[8pt]2 =& 2\\[8pt]3 =& 3\\[8pt]2 =& 2\\[8pt]2 =& 2\\[8pt]4 =& 2\cdot2\\[8pt]4 =& 2\cdot2\\[8pt]\end{aligned}$$Note that in this example numbers do not have any common factors.
Step 3 : Multiply the boxed numbers together:
Since there is no boxed numbers we conclude that $~\color{blue}{ \text{GCD = 1} } $.
