If a=23×32×5 and b=24×3×72, then which of the following is true?
HCF = 23×3
LCM = 24×32×5×72
HCF is the product of common prime factors with their lowest power.
LCM is the product of prime factors with their highest power.
Given : a=23×32×5 and b=24×3×72
⇒ HCF of a and b = 23×3 ( Taking the product of lowest powers of common factors)
LCM of a and b = 24×32×5×72 (Taking the product of prime factors with their highest power)
