Question 84
Suppose $a$ and $b$ be positive integers not exceeding $100$ such that
$$
a b = \left(\frac{\operatorname{lcm}(a, b)}{\operatorname{gcd}(a, b)}\right)^2
$$
Compute the largest possible value of $a + b$.
$$
a b = \left(\frac{\operatorname{lcm}(a, b)}{\operatorname{gcd}(a, b)}\right)^2
$$
Compute the largest possible value of $a + b$.
