Question

find the LCM and HCF of 70 80 and 120​

Answer 1

Answer:

70 = 5×7×2

80 = 7×2×2×2×2

120 = 2×2×2×3×5

Lcm = 2×2×2×2×3×5×5×7

= 8400

Hcf = 2×2×2×2

= 16

Plsssssss mark as the brainliest answer ❤❤❤

Answer 2

Answer:

HCF = 10 ; LCM = 1680

Step-by-step explanation:

HCF is the smallest powers of shared factors

LCM is the highest power of each factor whether it is shared or not ( does not matter)

70 = 2*5*7. (Exponential forms)

80= (2)^4 *5

120 = (2)^3 *3*5

HCF = 2*5 = 10

LCM = (2)^4 * 5 * 3 * 7

= 1680

hop this helps dear..
