Question

Find the HCF and LCM of 126 and 156 using prime factorization method

Answer 1

Facors of 126 = 2 x 3 x 3 x 7

Factors of 156 = 2 x 2 x 3 x 13

LCM = 2 x 2 x 3 x 3 x 7 x 13 = 3276

HCF = 2 x 3 = 6

Answer 2

Answer:

Step-by-step explanation:

The Factor of 126=2×3²×7

and 156=2²×3×13

Hcf =2×3=6
