LCM of 8,15, and 20 \r
\n" ); document.write( "\n" ); document.write( "Method for finding LCM.
\n" ); document.write( "1. convert each number to its prime-factor form, as follows:
\n" ); document.write( "8=2*2*2
\n" ); document.write( "15=3*5
\n" ); document.write( "20=2*2*5\r
\n" ); document.write( "\n" ); document.write( "2. The LCM must contain each prime factor to the highest
\n" ); document.write( "power indicated, as follows:
\n" ); document.write( "2 must be there are 2^3
\n" ); document.write( "3 must be there as 3
\n" ); document.write( "5 must be there as 5\r
\n" ); document.write( "\n" ); document.write( "3. Find the product of these, as follows:
\n" ); document.write( "2^3*3*5 = 8*15= 120
\n" ); document.write( "That is the LCM of 8, 15, and 20\r
