Find the HCF and LCM of , and .

Answer :

Given: The fractions , and .


To Find: The HCF and LCM of the numbers.


Formula Used:


LCM=lcm of (numerators)/hcf of (denominators)


HCF= HCF of (numerators)/LCM of (denominators)


Explanation:


HCF of numerators (8,10,16) = 2


HCF of denominators (9,27,81) = 9.


LCM of numerators (8,10,16) = 80


LCM of denominators (9,27,81) = 81.


So HCF of fraction = HCF of numerator/ LCM of denominator



and LCM of fraction = LCM of numerator/HCF of denominator
