Answer:
Step-by-step explanation:
A = 2⁵ * 3⁷ * 5
B = 2⁸ * 3³ * 7
HCF = 2⁵ * 3³
HCF is the common factors found in both A & B. In common factors write the factor with minimum power
LCM = 2⁸ * 3⁷ * 5 * 7
LCM -> Write the common factors with maximum power and write all the other factors that are not common.
