Sentence 41: \(U\left( {32} \right) \) is:

A. \(U\left( {32} \right) = \left\{ {1;2;4;8;16;24;32} \right\}\)

B. \(U\left( {32} \right) = \left\{ {1;2;4;16;32} \right\}\)

C. \(U\left( {32} \right) = \left\{ {1;2;4;8;16;32} \right\}\)

D. \(U\left( {32} \right) = \left\{ {1;2;4;6;8;16;32} \right\}\)

Notice that 32 is divisible by 1; 2; 4; 8; 16; 32 so:

\(U\left( {32} \right) = \left\{ {1;2;4;8;16;32} \right\}\)
