Question

find the LCM and HCF of 6,72 and 120 using prim factarization method .also verify that LCM× HCF ≠ product of three numbers​

Answer 1

Answer:

6 = 2 × 3, 72 = 2×2×2× 3×3 , 120 = 2×2×2× 3 × 5

So, HCF (6, 72, 120) = 2× 3

= 2 × 3 = 6

LCM (6, 72, 120) = 2×2×2 × 3×3 × 5= 360

Note: 6 × 72 × 120 ≠ HCF (6, 72, 120) × LCM (6, 72, 120). So, the product of three numbers is not equal to the product of their HCF and LCM
