 Problem : 10 [ HCF_LCM ]       Solve this type of problem 10. LCM of two nos is 14 times their HCF. The sum of LCM and HCF is 600 . If one no is 280 , then find the other no ? Show Answer A: "LCM" = 14" HCF""LCM + HCF " = 600=> 14 " HCF + HCF " = 600=> 15 " HCF " = 600=> "HCF " = 600 / 15 = 40Here, "LCM" = 14 " HCF":. "LCM " = 14 * 40 = 560.:. "Other No " = ( "HCF" * "LCM" ) / ("Given No"} = ( 40 * 560 ) / 280 = 80.
