Question

$F_x$ is the set of positive integer factors of $x$. For example, $F_9 = \{1, 3, 9\}$. List the elements of $F_{24}$, $F_{18} \cap F_{12}$. Show that $n(F_{16}) = 5$. Find a possible value of $x$ such that $F_x \subseteq F_{32}$, $n(F_x) = 3$. Take $x$ to be a positive integer.

Accepted Answer

(a)(i) $F_{24}=\{1,2,3,4,6,8,12,24\}$ (ii) $F_{18}\cap F_{12}=\{1,2,3,6\}$ (b) $n(F_{16})=5$ (c)(i) $x=4$ (ii) $x=4$
