A whistle blows every 14 minutes and a bell rings every 12 minutes.
\n" ); document.write( " If the whistle and bell both sound together at 12
\n" ); document.write( ":
\n" ); document.write( "Find the least common multiple of 12 and 14, prime factor both:
\n" ); document.write( "12: 2,2,3
\n" ); document.write( "14: 2,7
\n" ); document.write( "then 2*2*3*7 = 84 is the LCM of 12 and 14
\n" ); document.write( ":
\n" ); document.write( "84 minutes = 1 hr 24 min
\n" ); document.write( ":
\n" ); document.write( "12:00 + 1:24 = 1:24 PM \n" ); document.write( "

\n" );
