We know that 
     HCF×LCM=FIRST NO.×SECOND NO.------------------------------(1)
PRODUCT OF TWO NO. IS 720 
AND HCF=LCM/4
PUTTING IN THE EQUATION (1)
                                 LCM+LCM/4=720
                                 5LCM/4= 720
                                 5LCM=720×4
                                   LCM=2880/5=576
AND WE KNOW THAT HCF=LCM/4
                                 HCF=576/4=144
THEREFORE HCF OF THEIR WAGES IS 144
