Algebra.Com's Answer #128981 by vleith(2983)![]() ![]() ![]() You can put this solution on YOUR website! Find the prime factors in each denominator. Then use that info to find the LCD \n" ); document.write( "3/4,3/8,1/5 \n" ); document.write( "4 has factors 2*2 \n" ); document.write( "8 has factors 2*2*2 \n" ); document.write( "5 has factor 5\r \n" ); document.write( "\n" ); document.write( "Now look at the factors for each denominator and select the ones that occur 'the most' in any one of them. \n" ); document.write( "We have 2 2s in 4 and 3 2s in 8. So pick 3 2s (2 *2 *2) \n" ); document.write( "We have a factor of 5 in one and zero 5s in the others. So use one 5 \n" ); document.write( "Then find the product and you have the LCD \n" ); document.write( " |
