Manjushree Hiremat 7 years, 11 months ago

HCF×LCM=A×B 2079×27=189×B 56133=189×B B=56133÷189 B=297 To know whether this answer is wrote or wrong follow this method A×B=189×297 = 56133 HCF ×LCM =56133 So by multiplying HCF and LCM ,A and B we should get same answer then ur calculation is right Hope it helps u
