Question

Find the H.C.F and L.C.M by prime factorisation method: 12, 24, and 36.​

Answer 1

Answer:

LCM of 12,24and 36=72

HCF of 12,24and 36 =12

Prime factors =2×2×3×3×2=72

Answer 2

12=3×2×2

24=3×2×2×2

36=3×3×2×2

therefore hcf of 12,24 and 36 is 3×2×2=12

lcm=3×2×2×2×3=72

so HCF=12 and LCM=72
