# Find the HCF and LCM of , and .

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
