find the prime factors for each number, and multiply the factors as many times as they most frequently occur
\n" ); document.write( "(the example is easier to see)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "factors of 9 ... 3,3
\n" ); document.write( "factors of 12 ... 2,2,3
\n" ); document.write( "factors of 16 ... 2,2,2,2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "so the factors of the denominator will be 3,3 (from the 9) and 2,2,2,2 (from the 16) ... 9*16=144\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the factors from the 12 (two 2's and one 3) are included in the factors of the 9 (two 3's) and the 16 (four 2's)
\n" ); document.write( "
\n" );
