MiniQuestion Explanation

It says "The prime factorization of 120 is 23 × 3 × 5, so its sum of factors is (1 + 2 + 2^3)..." in the explanation. I think the 2^2 is missing.

@divinedolphin Hi there, you are really good at catching these typos! You're a big help. I'll fix this right now. Thank you so much.
By the way, you can type (1 + 2 + 2^3)... in math format, by typing this:
\\(1 + 2 + 2^3 \\)
which will give you
$$ 1 + 2 + 2^3 $$
