Question

Find the HCF of 96 and 404 by the prime factorisation method. Hence,
find their LCM.

Answer 1

HCF of 96 and 404 by prime factorisation method:-
Since, 96 = 2 × 2 × 2 × 2 × 2 × 3
and, 404 = 2 × 2 × 101
So, HCF of 96 and 404 = Product of common prime factors
                                  = 2 × 2 = 4
LCM = 2 × 2 × 2 × 2 × 2 × 101 × 3
        = 9696

Answer 2

Answer:

96=2×2×2×2×2×3

404=2×2×10

HCF=4

LCM=9696

(96×404)=9696
