Question

Find Lcm and HcF of 12,15,20,27​

Answer 1

Answer:

12 = 2×2×3 = 2^2 ×3^1

15 = 3× 5

20 = 2×2×5 = 2^2×5

27 = 3×3×3 = 3^3

HCF = 1

LCM = 2^2 × 3^3 × 5 = 540

Answer 2

Answer:

1

Step-by-step explanation:

12 = 3 x 4

15 = 3 x 5

20 = 2x2x5

27 =3x3x3

hcf = product of least power of common factors

therefore hcf is 1
