Question

Using prime factorization method, find hcf and lcm of 80, 124 and 144. Also, show that hcfx lcm = product of three numbers.

Answer 1

Answer:

Step-by-step explanation:

By prime factorisation

80= 2×2×2×2×5

124=2×2×31

144=2×2×2×13

HCF= 2×2

=4

LCM=2×2×2×2×2×13×31

=12896

Answer 2

Answer:

LCM is 22380

HCF is 4

Step-by-step explanation:

80=2×2×2×2×5

124=2×2×31

144=2×2×2×2×3×3

so

LCM is 2×2×2×2×31×5×3×3=22320

HCF is 2×2=4
