Answer:

QUESTION :-

The following pairs of numbers, show that the product of their HCF and LCM equal their product

i) 21,28

ii) 144, 198

iii) 36,76

iv) 120,350

SOLUTION :-

i )21,28

LCM(21,28) = 84

HCF(21,28) = 7

21×28=84×7

588=588

LHS=RHS

ii) 144,198

LCM(144,196) = 7056

HCF(144,196) = 4

144×198=7056×4

28,224=28,224

LHS =RHS

iii) 36,76

LCM(36,76) = 684

HCF(36,76) = 4

36×76=684×4

2,736=2,736

LHS =RHS

iv) 120,350

LCM(120,350) = 4200

HCF(120,350) = 10

120×350=4200×10

42,000=42,000

LHS =RHS
