Solution :-

LCM : Least common multiple

GCD : greatest common divisor

______________________________

21 yx^2 = 3 × 7 × y × x × x

35 xy^2 = 5 × 7 × x × y × y

  • LCM = 3 × 5 × 7 × y × y × x × x
  • LCM = 105 x^2 y^2

  • GCD = 7 × x × y = 7 xy

______________________________

we have to verify

that

21 y x^2 × 35x y^2 = LCM × GCD

LHS = 21 yx^2 × 35 xy^2

LHS = 735 x^3 y^3

RHS = LCM × GCD

RHS = 105 x^2 y^2 × 7 x y

RHS = 735 x^3 y^3

LHS = RHS

verified.
