	$36=2^2 3^2 48=2^4 3 gcf(36, 48)=2^2 3=12 ⇒ x=2^i 3^j k with 2≤i∧1≤j lcm(36, 48)=2^4 3^2 =144=((432)/3) ⇒ x=2^i 3^j with i≤4∧j=3 ⇒ 2≤i≤4∧j=3 ⇒ x∈{2^2 3^3 , 2^3 3^3 , 2^4 3^3 }={108, 216, 432}$
	$36 = 2^{2} 3^{2}$ $48 = 2^{4} 3$ $gcf (36, 48) = 2^{2} 3 = 12 \Rightarrow x = 2^{i} 3^{j} k with 2 ⩽ i \land 1 ⩽ j$ $lcm (36, 48) = 2^{4} 3^{2} = 144 = \frac{432}{3} \Rightarrow x = 2^{i} 3^{j} with i ⩽ 4 \land j = 3$ $\Rightarrow 2 ⩽ i ⩽ 4 \land j = 3$ $\Rightarrow x \in {2^{2} 3^{3}, 2^{3} 3^{3}, 2^{4} 3^{3}} = {108, 216, 432}$
