Question

EX 2) The cost of a pattachitra is Rs 455, The cost of applique work is Rs 350. What is HCF and LCM of these two costs?​

Answer 1

455=5×7×13

350=5×7×5×2

LCM = Least common multiple

LCM= 5×7×13×5×2=4550( considering all multiples but repeated nos in both cases should be considered only once)

HCF= Highest common factor

HCF= 5×7=35 ( considering only common multiples)
