 A positive integer $n$ is loose if it has six positive divisors and satisfies the property that any two positive divisors $a<b$ of $n$ satisfy $b \geq 2 a$. Compute the sum of all loose positive integers less than 100. Show your work in <think> </think> tags. And return the final answer in <answer> </answer> tags.<|im_end|>
