Sentence 46: \(U\left( 8 \right) \) is:

A. \(U\left( 8 \right) = \left\{ {1;2;4;6;8} \right\}\)

B. \(U\left( 8 \right) = \left\{ {1;2;3;4;8} \right\}\)

C. \(U\left( 8 \right) = \left\{ {2;4;8} \right\}\)

D. \(U\left( 8 \right) = \left\{ {1;2;4;8} \right\}\)

From 1 to 8, we see that 8 is divisible by 1, 2, 4, 8, so:

\(U\left( 8 \right) = \left\{ {1;2;4;8} \right\}\)
